Neufeld and I. Vitev Categories: hep-ph nucl-ex nucl-th Comments: 4 pages, 4 figures \\ Tagged jet measurements provide a promising experimental channel to quantify the similarities and differences in the mechanisms of jet production in proton-proton and nucleus-nucleus collisions. We present the first calculation of the transverse momentum asymmetry of Z^0/gamma^*-tagged jet events in sqrt{s}=2.76$ TeV reactions at the LHC. Our results combine the O(G_F\alpha_s^2) perturbative cross sections with the radiative and collisional processes that modify parton showers in the presence of dense QCD matter. We find that a strong asymmetry is generated in central lead-lead reactions that has little sensitivity to the fluctuations of the underlying soft hadronic background. We present theoretical model predictions for its shape and magnitude. \\ ( http://arxiv.org/abs/1202.5556 , 551kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5584 Date: Fri, 24 Feb 2012 23:43:24 GMT (107kb) Title: A QCD-like theory with the ZN symmetry Authors: Hiroaki Kouno, Yuji Sakai, Takahiro Makiyama, Kouhei Tokunaga, Takahiro Sasaki and Masanobu Yahiro Categories: hep-ph hep-lat nucl-th Comments: 12 pages, 23 figures Report-no: SAGA-HE-271 \\ We propose a QCD-like theory with the Z_N symmetry. The flavor-dependent twisted boundary conditions (TBC) in temporal direction are imposed on the SU(N) gauge theory with fundamental quarks with N degenerate flavors. The QCD-like theory is useful to understand the mechanism of confinement, since the Z_N symmetry is exact. Dynamics of the QCD-like theory is studied by imposing the TBC on the Polyakov-extended Nambu-Jona-Lasinio (PNJL) model. The TBC model is applied to two cases of N=2 and 3. The first-order deconfinement transition takes place at some temperature Tc. The perfect color confinement in which the Polyakov loop is zero occurs below Tc, while the Z_N symmetry is spontaneously broken above T_c. The perfect color confinement restores the flavor symmetry and finally induces the flavor confinement. Above Tc, both color and flavor are deconfined. The present model prediction can be tested in future by lattice QCD, since the QCD-like theory has no sign problem. \\ ( http://arxiv.org/abs/1202.5584 , 107kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5592 Date: Sat, 25 Feb 2012 00:44:12 GMT (740kb) Title: Single slepton production associated with a top quark at LHC in NLO QCD Authors: Li Xiao-Peng, Guo Lei, Ma Wen-Gan, Han Liang, Zhang Ren-You, and Wang Shao-Ming Categories: hep-ph hep-ex Comments: 33 pages, 18 figures, accepted by EPJC \\ Single slepton production in association with a top quark at the CERN Large Hadron Collider (LHC) is one of the important processes in probing the R-parity violation couplings. We calculate the QCD next-to-leading order (NLO) corrections to the $pp \to t\slep^{-}(\bar{t}\slep^{+})+X$ process at the LHC and discuss the impacts of the QCD corrections on kinematic distributions. We investigate the dependence of the leading order (LO) and the NLO QCD corrected integrated cross section on the factorization/renormalization energy scale, slepton, stop-quark and gluino masses. We find that the uncertainty of the LO cross section due to the energy scale is obviously improved by the NLO QCD corrections, and the exclusive jet event selection scheme keeps the convergence of the perturbative series better than inclusive scheme. The results show that the polarization asymmetry of the top-quark will be reduced by the NLO QCD corrections, and the QCD corrections generally increase with the increment of $\tilde{t}_1$ or $\tilde{g}$ mass value. \\ ( http://arxiv.org/abs/1202.5592 , 740kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5641 Date: Sat, 25 Feb 2012 11:13:14 GMT (21kb) Title: The QCD Critical End Point Under Strong Magnetic Fields Authors: Sidney S. Avancini, D\'ebora P. Menezes, Marcus B. Pinto and Constan\c{c}a Provid\^encia Categories: hep-ph Comments: 5 pages, 2 figures \\ We use the three-flavor Nambu--Jona-Lasinio model, which includes strangeness and quark physical masses in the mean field approximation, to investigate the influence of strong magnetic fields on the QCD phase diagram covering the whole $T-\mu$ plane. It is found that the size of the first order transition line increases as the field strength increases so that a larger coexistence region for hadronic and quark matter should be expected for strong magnetic fields. The location of the critical end point is also affected by the presence of magnetic fields which invariably increase the temperature value at which the first order line terminates. On the other hand, the critical end point chemical potential value displays a subtle oscillation around the B=0 value for magnetic fields within the $10^{17}-10^{20} \, {\rm G}$ range. These findings may have non trivial consequences for the physics of magnetars and heavy ion collisions. \\ ( http://arxiv.org/abs/1202.5641 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5644 Date: Sat, 25 Feb 2012 12:22:50 GMT (176kb) Title: QCD at work: from lepton to hadron colliders and back Authors: Andrea Banfi Categories: hep-ph Comments: 14 pages, 4 figures. Presented at "Linear Collider 2011: Understanding QCD at Linear Colliders in searching for old and new physics", 12-16 September 2011, ECT*, Trento, Italy \\ The astounding Physics results obtained with high-energy colliders in the last two decades owe much to an impressive progress in the understanding of the dynamics of strong interactions. I give here a personal overview of how the advance in QCD triggered by the Physics of hadronic final states at LEP has been exploited for New Physics searches at the LHC. Conversely, the need for precision calculations for LHC experiments has stimulated a huge progress in the understanding of the all-order structure of gauge theories. These results raise high expectations on the status of QCD at the start of a linear collider. \\ ( http://arxiv.org/abs/1202.5644 , 176kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5646 Date: Sat, 25 Feb 2012 12:45:15 GMT (27kb) Title: Algebraic description of external and internal attributes of fundamental fermions Authors: Ikuo S. Sogami Categories: hep-ph Comments: 15pages, no figure, Presented at QTS7 2011 Report-no: MISC-2012-06 Journal-ref: Journal of Physics: Conference Series, Vol. 343, 012113 2012 DOI: 10.1088/1742-6596/343/1/012113 \\ To describe external and internal attributes of fundamental fermions, a theory of multi-spinor fields is developed on an algebra, a {\it triplet algebra}, which consists of all the triple-direct-products of Dirac \gamma-matrices. The triplet algebra is decomposed into the product of two subalgebras, an external algebra and an internal algebra, which are exclusively related with external and internal characteristic of the multi-spinor field named {\it triplet fields}. All elements of the external algebra which is isomorphic to the original Dirac algebra $A_\gamma$ are invariant under the action of permutation group $S_3$ which works to exchange the order of the $A_\gamma$ elements in the triple-direct-product. The internal algebra is decomposed into the product of two $4^2$ dimensional algebras, called the family and color algebras, which describe the family and color degrees of freedom. The family and color algebras have fine substructures with "trio plus solo" conformations which are irreducible under the action of $S_3$. The triplet field has trio plus solo family modes with ordinary tricolor quark and colorless solo lepton components. To incorporate the Weinberg-Salam mechanism, it is required to introduce two types of triplet fields, a left-handed doublet and right-handed singlets of electroweak iso-spin. It is possible to qualify the Yukawa interaction and to make a new interpretation of its coupling constants naturally in an intrinsic mechanism of the triplet field formalism. The ordinary Higgs mechanism leads to a new type of the Dirac mass matrices which can explain all data of quark sector within experimental accuracy. \\ ( http://arxiv.org/abs/1202.5646 , 27kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5652 Date: Sat, 25 Feb 2012 15:00:37 GMT (45kb) Title: Test of Little Higgs Mechanism at Future Colliders Authors: Shigeki Matsumoto Categories: hep-ph Comments: 6 pages, 6 figures. Proceedings of International Linear Collider Workshop (LCWS11), Sep. 26-30, 2011, Granada, Spain \\ In the little higgs scenario, several coupling constants are related to each other to guarantee the stability of the higgs boson mass at one-loop level. This relation is called the little higgs mechanism. We discuss how accurately the relation can be tested at future $e^+e^-$ colliders, with especially focusing on the top sector of the scenario using a method of effective lagrangian. In order to test the mechanism, it is important to measure the Yukawa coupling of the top partner. Higgs associated and threshold productions of the top partner are found to be the best processes for this purpose. \\ ( http://arxiv.org/abs/1202.5652 , 45kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5661 Date: Sat, 25 Feb 2012 16:37:36 GMT (127kb) Title: Single Production of Fourth Family Sneutrino via RPV Couplings at Linear Colliders Authors: O. Cakir, S. Kuday, I. T. Cakir, S.

We study the decays of $\tilde{\nu}_{4}$ into different flavor dilepton $e^{\pm}\mu^{\mp}$ via R-parity violation. We discuss the constraints on the R-parity violating couplings $(\lambda_{411},\lambda_{412})$ of the fourth family sneutrino at the linear collider energies. \\ ( http://arxiv.org/abs/1202.5661 , 127kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5704 Date: Sat, 25 Feb 2012 22:59:39 GMT (42kb,D) Title: Flavour-Changing Decays of a 125 GeV Higgs-like Particle Authors: Gianluca Blankenburg, John Ellis, Gino Isidori Categories: hep-ph hep-ex Comments: 8 pages, 1 figure Report-no: CERN-PH-TH/2012-049, KCL-PH-TH/2012-09, LCTS/2012-05 \\ The ATLAS and CMS experiments at the LHC have reported the observation of a possible excess of events corresponding to a new particle $h$ with mass $\sim 125$ GeV that might be the long-sought Higgs boson, or something else. Decyphering the nature of this possible signal will require constraining the couplings of the $h$ and measuring them as accurately as possible. Here we analyze the indirect constraints on flavour-changing $h$ decays that are provided by limits on low-energy flavour-changing interactions. We find that indirect limits in the quark sector impose such strong constraints that flavour-changing $h$ decays to quark-antiquark pairs are unlikely to be observable at the LHC. On the other hand, the upper limits on lepton-flavour-changing decays are weaker, and the experimental signatures less challenging. In particular, we find that either ${\mathcal B}(h \to \tau \bar \mu + \bar \mu \tau)$ or ${\mathcal B}(h \to \tau \bar e + \bar e \tau) $ could be ${\cal O}(10)%$, i.e., comparable to ${\mathcal B}(h \to \tau^+ \tau^-)$ and potentially observable at the LHC. \\ ( http://arxiv.org/abs/1202.5704 , 42kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5717 Date: Sun, 26 Feb 2012 02:12:46 GMT (1280kb) Title: Vacuum stability, neutrinos, and dark matter Authors: Chian-Shu Chen and Yong Tang Categories: hep-ph Comments: 18 pages, 15 figures \\ Motivated by the discovery hint of the Standard Model (SM) Higgs mass around 125 GeV at the LHC, we study the vacuum stability and perturbativity bounds on Higgs scalar of the SM extensions including neutrinos and dark matter (DM). Guided by the SM gauge symmetry and the minimal changes in the SM Higgs potential we consider two extensions of neutrino sector (Type-I and Type-III seesaw mechanisms) and DM sector (a real scalar singlet (darkon) and minimal dark matter (MDM)) respectively. The darkon contributes positively to the $\beta$ function of the Higgs quartic coupling $\lambda$ and can stabilize the SM vacuum up to high scale. Similar to the top quark in the SM we find the cause of instability is sensitive to the size of new Yukawa couplings between heavy neutrinos and Higgs boson, namely, the scale of seesaw mechanism. MDM and Type-III seesaw fermion triplet, two nontrivial representations of $SU(2)_{L}$ group, will bring the additional positive contributions to the gauge coupling $g_{2}$ renormalization group (RG) evolution and would also help to stabilize the electroweak vacuum up to high scale. \\ ( http://arxiv.org/abs/1202.5717 , 1280kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5781 Date: Sun, 26 Feb 2012 17:10:46 GMT (127kb) Title: Status of MadLoop/aMC@NLO Authors: Roberto Pittau Categories: hep-ph Comments: 8 pages, 4 figures.

In this model, all vacuum expectation values (VEVs) of the yukawaons, , are described in terms of a fundamental VEV matrix <\Phi_0> as in the previous yukawaon model, but the assignments of quantum number for fields are different from the previous ones: the fundamental yukawaon \Phi_0 is assigned to (3,3) of U(3) \times U(3), which is broken into (3,1+2) of U(3) \times S_3, although quarks and leptons are still assigned to triplets of U(3) and yukawaons Y_f are assigned to 6^* of U(3). Then, VEV relations among Yukawaons become more concise considerably than the previous yukawaon models. By adjusting parameters, we can fit not only quark mixing parameters but also lepton mixing parameters together with their mass ratios. \\ ( http://arxiv.org/abs/1202.5815 , 368kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5816 Date: Mon, 27 Feb 2012 02:30:08 GMT (23kb) Title: Neutrino properties in E6 x SU(2)F SUSY GUT with spontaneous CP violation Authors: Nobuhiro Maekawa, Kenichi Takayama Categories: hep-ph Comments: 18 pages \\ We examined the neutrino sector in E6 x SU(2)F SUSY GUT with spontaneous CP violation. At a glance, the discrete symmetry, which is introduced in order to solve the SUSY CP problem, constrains the allowed operators too strongly for the neutrino sector to be consistent with the experimental data, i.e., the mu neutrino becomes massless as commented in the previous paper. We showed that this issue can be solved if some operators are taken into account. And we saw that such operators do not play an important role in studying quark and charged lepton sectors. The predictions on the neutrino masses and mixings are the same as the E6 models, which are consistent with various experiments on the neutrino oscillations. \\ ( http://arxiv.org/abs/1202.5816 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5821 Date: Mon, 27 Feb 2012 03:48:11 GMT (336kb) Title: A SM-like Higgs near 125 GeV in low energy SUSY: a comparative study for MSSM and NMSSM Authors: Junjie Cao, Zhaoxia Heng, Jin Min Yang, Yanming Zhang, Jingya Zhu Categories: hep-ph Comments: 22 pages, 9 figs \\ Motivated by the recent LHC hints of a Higgs boson around 125 GeV, we assume a SM-like Higgs with the mass 123-127 GeV and study its implication in low energy SUSY by comparing the MSSM and NMSSM. We consider various experimental constraints at 2-sigma level (including the muon g-2 and the dark matter relic density) and perform a comprehensive scan over the parameter space of each model. Then in the parameter space which is allowed by current experimental constraints and also predicts a SM-like Higgs in 123-127 GeV, we examine the properties of the sensitive parameters (like the top squark mass and the trilinear coupling A_t) and calculate the rates of the di-photon signal and the VV^* (V=W,Z) signals at the LHC. Our typical findings are: (i) In the MSSM the top squark and A_t must be large and thus incur some fine-tuning, which can be much ameliorated in the NMSSM; (ii) In the MSSM a light stau is needed to enhance the di-photon rate of the SM-like Higgs to exceed its SM prediction, while in the NMSSM the di-photon rate can be readily enhanced in several ways; (iii) In the MSSM the signal rates of pp->h->VV^* at the LHC are always suppressed compared with their SM predictions, while in the NMSSM they may get enhanced significantly; (iv) A large part of the parameter space so far survived will be soon covered by the expected XENON100(2012) sensitivity (especially for the NMSSM). \\ ( http://arxiv.org/abs/1202.5821 , 336kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5828 Date: Mon, 27 Feb 2012 06:03:41 GMT (9kb) Title: Matter-Dark-Matter Correspondence in Left-Right Symmetry Authors: Ernest Ma (UC Riverside) Categories: hep-ph astro-ph.CO Comments: 9 pages, no figure Report-no: UCRHEP-T516 (Feb 2012) \\ In an unconventional realization of left-right symmetry, the particle corresponding to the left-handed neutrino nu_L (with SU(2)_L interactions) in the right-handed sector, call it n_R (with SU(2)_R interactions), is not its Dirac mass partner, but a different particle which may be a dark-matter candidate. In parallel to leptogenesis in the SU(2)_L sector, asymmetric production of n_R may occur in the SU(2)_R sector. This mechanism is especially suited for n_R mass of order 1 to 10 keV, i.e. warm dark matter, which is a possible new paradigm for explaining the structure of the Universe at all scales. \\ ( http://arxiv.org/abs/1202.5828 , 9kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5851 Date: Mon, 27 Feb 2012 08:28:17 GMT (815kb) Title: Production of dark matter axions from collapse of string-wall systems Authors: Takashi Hiramatsu, Masahiro Kawasaki, Ken'ichi Saikawa and Toyokazu Sekiguchi Categories: hep-ph astro-ph.CO Comments: 21 pages, 7 figures Report-no: ICRR-Report-608-2011-25; IPMU12-0025; YITP-12-9 \\ We analyze the spectrum of axions radiated from collapse of domain walls, which have received less attention in the literature. The evolution of topological defects related to the axion models is investigated by performing field-theoretic lattice simulations. We simulate the whole process of evolution of the defects, including the formation of global strings, the formation of domain walls and the annihilation of the defects due to the tension of walls. The spectrum of radiated axions has a peak at the low frequency, which implies that axions produced by the collapse of domain walls are not highly relativistic. We revisit the relic abundance of cold dark matter axions and find that the contribution from the decay of defects can be comparable with the contribution from strings. This result leads to a severer upper bound on the axion decay constant. \\ ( http://arxiv.org/abs/1202.5851 , 815kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5867 Date: Mon, 27 Feb 2012 09:27:53 GMT (42kb) Title: Scalar Decay Constant and Yukawa Coupling in Walking Technicolor Models Authors: Michio Hashimoto Categories: hep-ph Comments: 4 pages, 2 figures.

Descotes-Genon (LPT, Orsay) and M. Knecht (CPT, Marseille) Categories: hep-ph hep-ex Comments: 57 pages, 12 figures Report-no: LPT-ORSAY/12-18; CPT-P002-2012 \\ Dispersive representations of the pi-pi scattering amplitudes and pion form factors, valid at two-loop accuracy in the low-energy expansion, are constructed in the presence of isospin-breaking effects induced by the difference between the charged and neutral pion masses. Analytical expressions for the corresponding phases of the scalar and vector pion form factors are computed. It is shown that each of these phases consists of the sum of a "universal" part and a form-factor dependent contribution. The first one is entirely determined in terms of the pi-pi scattering amplitudes alone, and reduces to the phase satisfying Watson's theorem in the isospin limit. The second one can be sizeable, although it vanishes in the same limit. The dependence of these isospin corrections with respect to the parameters of the subthreshold expansion of the pi-pi amplitude is studied, and an equivalent representation in terms of the S-wave scattering lengths is also briefly presented and discussed. In addition, partially analytical expressions for the two-loop form factors and pi-pi scattering amplitudes in the presence of isospin breaking are provided. \\ ( http://arxiv.org/abs/1202.5886 , 726kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5902 Date: Mon, 27 Feb 2012 11:56:31 GMT (63kb) Title: Vector WIMP Miracle Authors: Tomohiro Abe, Mitsuru Kakizaki, Shigeki Matsumoto, Osamu Seto Categories: hep-ph Comments: 11 pages, 4 figures Report-no: UT-HET-063; IPMU12-0029; HGU-CAP-14 \\ Weakly interacting massive particle (WIMP) is well known to be a good candidate for dark matter, and it is also predicted by many new physics models beyond the standard model at the TeV scale. We found that, if the WIMP is a vector particle (spin one particle) which is associated with some gauge symmetry broken at the TeV scale, the higgs mass is often predicted to be 120--125 GeV, which is very consistent with the result of higgs searches recently reported by ATLAS and CMS collaborations at the Large Hadron Collider experiment. In this letter, we consider the vector WIMP using a non-linear sigma model in order to confirm this result as general as possible in a bottom-up approach. Near-future prospects to detect the vector WIMP at both direct and indirect detection experiments of dark matter are also discussed. \\ ( http://arxiv.org/abs/1202.5902 , 63kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5929 Date: Mon, 27 Feb 2012 13:21:13 GMT (10kb) Title: Mesons Mass Spectrum in a Modified Soft-Wall AdS/QCD Model Authors: Keita Kaniba Mady and Dicko Younouss Hameye Categories: hep-ph Comments: 8 pages, 1 figure \\ We modified the current soft wall model by considering the Non-conformal aspect low energy QCD. \\ ( http://arxiv.org/abs/1202.5929 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5942 Date: Mon, 27 Feb 2012 14:11:42 GMT (297kb) Title: The chiral and deconfinement phase transitions Authors: Fukun Xu and Mei Huang Categories: hep-ph Comments: 5 pages, 4 figures, Proceedings of the International Conference "Critical Point and Onset of Deconfinement - CPOD 2011", Wuhan, November 7-11, 2011 \\ By introducing the dressed Polayakov loop or dual chiral condensate as a candidate order parameter to describe the deconfinement phase transition for light flavors, we discuss the interplay between the chiral and deconfinement phase transitions, and propose the possible QCD phase diagram at finite temperature and density.

In addition to the color-singlet contribution, color-octet (CO) channels (especially the P-wave channel) up to $O(v^4)$ are all considered. Aside from direct production, the feed-down contributions from higher excited S-wave and P-wave $b\bar b$ states to $\Upsilon(1S)$ production are also included. We use the potential model estimates as input for color-singlet (CS) long-distance matrix elements (LDMEs). While for CO contributions, we find they can be approximately described by three LDMEs: $\mo{}{3}{S}{1}{8}$, $\mo{}{1}{S}{0}{8}$ and $\mo{}{3}{P}{0}{8}$. By fitting the Tevatron data we can determine some linear combinations of these LDMEs, and then use them to predict $\Upsilon(1S)$ production at the LHC. Our predictions are consistent with the new experimental data of CMS and LHCb. \\ ( http://arxiv.org/abs/1202.6012 , 999kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1202.5603 (*cross-listing*) Date: Sat, 25 Feb 2012 02:49:14 GMT (181kb) Title: Solution to Big-Bang Nucleosynthesis in Hybrid Axion Dark Matter Model Authors: Motohiko Kusakabe, A.B.

Production of vector meson pairs is clearly observed and their cross sections are measured for masses that range from threshold to 4.0 GeV. In addition to signals from well established spin zero and spin two charmonium states, there are clear resonant structures below charmonium threshold, which have not been previously observed. We report a spin-parity analysis for the new structures and determine the products of the $\etac$, $\chi_{c0}$, and $\chi_{c2}$ two-photon decay widths and branching fractions. \\ ( http://arxiv.org/abs/1202.5632 , 54kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5658 (*cross-listing*) Date: Sat, 25 Feb 2012 16:04:51 GMT (103kb) Title: Lorentz covariant nucleon self-energy decomposition of the nuclear symmetry energy Authors: Bao-Jun Cai, Lie-Wen Chen Categories: nucl-th astro-ph.SR hep-ph nucl-ex Comments: 6 pages, 2 figures \\ Using the Hugenholtz-Van Hove theorem, we derive analytical expressions for the nuclear symmetry energy $E_{sym}(\rho)$ and its density slope $L(\rho)$ in terms of the Lorentz covariant nucleon self-energies in isospin asymmetric nuclear matter. These general expressions are useful for understanding the Lorentz structure and the microscopic origin of the nuclear symmetry energy in relativistic covariant formulism. As an example, we analyze the Lorentz covariant nucleon self-energy decomposition of $E_{sym}(\rho)$ and $L(\rho)$ within the nonlinear $\sigma$-$\omega$-$\rho$-$\delta$ relativistic mean field model. \\ ( http://arxiv.org/abs/1202.5658 , 103kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5700 (*cross-listing*) Date: Sat, 25 Feb 2012 21:57:26 GMT (517kb) Title: The critical line of two-flavor QCD at finite isospin or baryon densities from imaginary chemical potentials Authors: P. Cea, L. Cosmai, M. D'Elia, A. Papa, F. Sanfilippo Categories: hep-lat hep-ph hep-th Comments: 11 pages, 11 figures, 4 tables \\ We determine the (pseudo)critical lines of QCD with two degenerate staggered fermions at nonzero temperature and quark or isospin density, in the region of imaginary chemical potentials; analytic continuation is then used to prolongate to the region of real chemical potentials. We obtain an accurate determination of the curvatures at zero chemical potential, quantifying the deviation between the case of finite quark and of finite isospin chemical potential. Deviations from a quadratic dependence of the pseudocritical lines on the chemical potential are clearly seen in both cases: we try different extrapolations and, for the case of nonzero isospin chemical potential, confront them with the results of direct Monte Carlo simulations. Finally we find that, as for the finite quark density case, an imaginary isospin chemical potential can strengthen the transition till turning it into strong first order. \\ ( http://arxiv.org/abs/1202.5700 , 517kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5860 (*cross-listing*) Date: Mon, 27 Feb 2012 08:54:08 GMT (393kb) Title: News from CERN, LHC Status and Strategy for Linear Colliders Authors: Rolf-Dieter Heuer Categories: physics.acc-ph hep-ex hep-ph \\ This paper presents the latest development at CERN, concentrating on the status of the LHC and the strategy for future linear colliders. The immediate plans include the exploitation of the LHC at its design luminosity and energy as well as upgrades to the LHC (luminosity and energy) and to its injectors. This may be complemented by a linear electron-positron collider, based on the technology being developed by the Compact Linear Collider and by the International Linear Collider and/or by a high-energy electron-proton collider. This contribution describes the various future directions, all of which have a unique value to add to experimental particle physics, and concludes by outlining key messages for the way forward. \\ ( http://arxiv.org/abs/1202.5860 , 393kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5974 (*cross-listing*) Date: Mon, 27 Feb 2012 15:32:56 GMT (40kb) Title: Direct photon observables from hydrodynamics and implications on the initial temperature and EoS Authors: Mate Csanad Categories: nucl-th hep-ph Comments: Presented at the VII Workshop on Particle Correlations and Femtoscopy (WPCF2011), Tokyo, Japan, September 20-24, 2011 \\ The expansion of the strongly interacting quark gluon plasma (sQGP) created in Au+Au collisions at RHIC can be described by hydrodynamical models. Hadrons are created after a freeze-out, thus their distribution describes the final state of the evolution. The earlier stages can be analyzed via penetrating probes like photon observables. These were measured in 2010 and 2011 by the PHENIX experiment. Here we analyze an analytic, 1+3 dimensional perfect relativistic hydrodynamic solution and calculate hadron and photon observables, such as transverse momentum spectra, elliptic flow and correlation (HBT) radii. We find that our model is not incompatible with the data, not even with the direct photon elliptic flow. From fitting the data, we find that early temperatures of the sQGP were well above the quark-hadron transition temperature, in the hottest point, the center of the fireball the temperature may have reached 507+-12 MeV. The equation of state of this quark matter can be described by an average sound speed of 0.36+-0.02. We also predict a photon source that is significantly larger in the out direction than in the side direction. \\ ( http://arxiv.org/abs/1202.5974 , 40kb) ------------------------------------------------------------------------------ \\ arXiv:1202.5978 (*cross-listing*) Date: Mon, 27 Feb 2012 15:45:12 GMT (36kb) Title: On the presence of twinlike models in cosmology Authors: D. Bazeia, J. D. Dantas Categories: hep-th hep-ph Comments: 4 pages, 2 figures; To appear in PRD \\ We study cosmological models described by a single real scalar field. We work within the first-order framework, and we show how the first-order equations simplify the investigation, leading to a direct search of twinlike theories. The procedure is used to introduce distinct models that support the same first-order equations, with the very same energy densities and pressure in flat spacetime. The presence of curvature forbids the construction of twinlike models in the cosmological scenario here investigated. \\ ( http://arxiv.org/abs/1202.5978 , 36kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0911.3030 (*cross-listing*) replaced with revised version Sun, 26 Feb 2012 04:32:41 GMT (0kb,I) Title: Quantum entanglement in soliton fractionalisation process Authors: S.
