We apply these results to calculate the imaginary part of the heavy-quark potential which is found to be smaller (in magnitude) than at vanishing viscosity. This implies a smaller decay width of quarkonium bound states in an anisotropic plasma. \\ ( http://arxiv.org/abs/0903.4703 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4705 Date: Thu, 26 Mar 2009 22:02:06 GMT (63kb) Title: A model independent spin analysis of fundamental particles using azimuthal asymmetries Authors: Fawzi Boudjema, Ritesh K. Singh Categories: hep-ph Comments: 42 pages, 7 figures, 4 tables \\ Exploiting the azimuthal angle dependence of the density matrices we construct observables that directly measure the spin of a heavy unstable particle. A novelty of the approach is that the analysis of the azimuthal angle dependence in a frame other than the usual helicity frame offers an independent cross-check on the extraction of the spin. Moreover, in some instances when the transverse polarisation tensor of highest rank is vanishing, for an accidental or dynamical reason, the standard azimuthal asymmetries vanish and would lead to a measurement with a wrong spin assignment. In a frame such as the one we construct, the correct spin assignment would however still be possible. The method gives direct information about the spin of the particle under consideration and the same event sample can be used to identify the spins of each particle in a decay chain. A drawback of the method is that it is instrumental only when the momenta of the test particle can be reconstructed. However we hope that it might still be of use in situations with only partial reconstruction. We also derive the conditions on the production and decay mechanisms for the spins, and hence the polarisations, to be measured at a collider experiment. As an example for the use of the method we consider the simultaneous reconstruction, at the partonic level, of the spin of both the top and the $W$ in top pair production in $e^+ e^-$ in the semi-leptonic channel. \\ ( http://arxiv.org/abs/0903.4705 , 63kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4715 Date: Thu, 26 Mar 2009 23:00:07 GMT (68kb,D) Title: Photoproduction of Pseudoscalar Mesons off Nuclei at Forward Angles Authors: S. Gevorkyan, A. Gasparian, L. Gan, I. Larin, M. Khandaker Categories: hep-ph Comments: 22 pages, 8 figures \\ With the advent of new photon tagging facilities and novel experimental technologies it has become possible to perform photoproduction cross section measurements of pseudoscalar mesons on nuclei with a percent level accuracy. The extraction of the radiative decay widths from these measurements at forward angles is done by the Primakoff method, which requires theoretical treatment of all processes participating in these reactions at the same percent level. In this work we review the theoretical approach to meson photoproduction amplitudes in the electromagnetic and strong fields of nuclei at forward direction. The most updated description of these processes are presented based on the Glauber theory of multiple scattering. In particular, the effects of final state interactions, corrections for light nuclei, and photon shadowing in nuclei are discussed. \\ ( http://arxiv.org/abs/0903.4715 , 68kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4735 Date: Fri, 27 Mar 2009 11:14:45 GMT (87kb) Title: Signatures of dark matter annihilation in the light of PAMELA/ATIC anomaly Authors: Kazunori Nakayama Categories: hep-ph Comments: Talk given at Dark2009, to appear in the proceedings; 8 pages, 5 figures \\ Recent measurements of cosmic-ray electron and positron fluxes by PAMELA and ATIC experiments may indicate the existence of annihilating dark matter with large annihilation cross section. We discuss its possible relation to other astrophysical/cosmological observations : gamma-rays, neutrinos, and big-bang nucleosynthesis. It is shown that they give stringent constraints on some annihilating dark matter models. \\ ( http://arxiv.org/abs/0903.4735 , 87kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4739 Date: Fri, 27 Mar 2009 07:03:37 GMT (177kb) Title: Dark matter in a Simplest Little Higgs with T-parity model Authors: Pat Kalyniak, Dmitriy Tseliakhovich Categories: hep-ph Comments: 11 pages, 10 figures \\ Little Higgs models may provide a viable alternative to supersymmetry as an extension of the Standard Model. After the introduction of a discrete $Z_2$ symmetry, dubbed T-parity into Little Higgs models they also contain a promising dark matter candidate. We investigate a heavy neutrino as a dark matter candidate in the Simplest Little Higgs with T-parity (SLHT) model. First we calculate relic density constraints on the parameter space of the model and then discuss collider signatures for the SLHT dark matter. \\ ( http://arxiv.org/abs/0903.4739 , 177kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4760 Date: Fri, 27 Mar 2009 10:23:14 GMT (43kb) Title: Three-loop on-shell Feynman integrals with two masses Authors: S.

In such a model, wherein the Standard Model gauge group is augmented by a broken $U(1)_{B-L}$ symmetry -- with $B(L)$ being the baryon(lepton) number -- the emerging $Z'$ mass is expected to be in the above energy range. It turns out that such machines, as compared to the Large Hadron Collider, display an additional potential in discovering a $Z'$ boson as well as in allowing one to uniquely study its properties at a level of precision well beyond that of the CERN machine. \\ ( http://arxiv.org/abs/0903.4777 , 62kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4797 Date: Fri, 27 Mar 2009 13:50:30 GMT (22kb) Title: On the description of exclusive processes beyond the leading twist approximation Authors: I.V.Anikin, D.Yu.Ivanov, B.Pire, L.Szymanowski, S.Wallon Categories: hep-ph Comments: 4 pages, 2 figures Report-no: CPHT-RR015-0309, LPT-ORSAY-09-23 \\ We describe hard exclusive processes beyond the leading twist approximation in a framework based on the Taylor expansion of the amplitude around the dominant light-cone directions. This naturally introduces an appropriate set of non-perturbative correlators whose number is minimalized after taking into account QCD equations of motion and the invariance under rotation on the light-cone. We show that the coordinate and momentum space descriptions are fully equivalent. \\ ( http://arxiv.org/abs/0903.4797 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4818 Date: Fri, 27 Mar 2009 15:08:58 GMT (195kb) Title: Nucleon electromagnetic and gravitational form factors from holography Authors: Zainul Abidin and Carl E.

We also calculate a gravitational or energy-momentum form factor by perturbing the metric from the static AdS solution. We consider both the hard-wall model where the AdS geometry is cutoff at z_0 and the soft-wall model where the geometry is smoothly cut off by a background dilaton field. \\ ( http://arxiv.org/abs/0903.4818 , 195kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4825 Date: Fri, 27 Mar 2009 15:29:02 GMT (27kb) Title: Medium-modified DGLAP evolution of fragmentation functions from large to small x Authors: S. Albino, B. A. Kniehl, R. Perez-Ramos Categories: hep-ph \\ The unified description of fragmentation function evolution from large to small x which was developed for the vacuum in previous publications is now generalized to the medium, and is studied for the case in which the complete contribution from the largest class of soft gluon logarithms, the double logarithms, are accounted for and with the fixed order part calculated to leading order. In this approach it proves possible to choose the remaining degrees of freedom related to the medium such that the distribution of produced hadrons is suppressed at large momenta while the production of soft radiation-induced charged hadrons at small momenta is enhanced, in agreement with experiment. Just as for the vacuum, our approach does not require further assumptions concerning fragmentation and is more complete than previous computations of evolution in the medium. \\ ( http://arxiv.org/abs/0903.4825 , 27kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4834 Date: Fri, 27 Mar 2009 16:00:45 GMT (59kb) Title: Photon - Jet Correlations and Constraints on Fragmentation Functions Authors: Z.

Werlen Categories: hep-ph Comments: 23 pages, 9 figures \\ We study the production of a large-pT photon in association with a jet in proton-proton collisions. We examine the sensitivity of the jet rapidity distribution to the gluon distribution function in the proton. We then assess the sensitivity of various photon + jet correlation observables to the photon fragmentation functions. We argue that RHIC data on photon-jet correlations can be used to constrain the photon fragmentation functions in a region which was barely accessible in LEP experiments. \\ ( http://arxiv.org/abs/0903.4834 , 59kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4849 Date: Fri, 27 Mar 2009 17:01:07 GMT (894kb) Title: Dark Matter Candidates Authors: Lars Bergstrom Categories: hep-ph Comments: 19 pages, 2 figures; invited contribution to NJP Focus Issue on "Dark Matter and Particle Physics" \\ An overview is given of various dark matter candidates. Among the many suggestions given in the literature, axions, inert Higgs doublet, sterile neutrinos, supersymmetric particles and Kaluza-Klein particles are discussed. The situation has recently become very interesting with new results on antimatter in the cosmic rays having dark matter as one of the leading possible explanations. Problems of this explanation and possible solutions are discussed, and the importance of new measurements is emphasized. If the explanation is indeed dark matter, a whole new field of physics, with unusual although not impossible mass and interaction properties may soon open itself to discovery. \\ ( http://arxiv.org/abs/0903.4849 , 894kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4869 Date: Fri, 27 Mar 2009 18:32:35 GMT (87kb) Title: SU(3)-breaking corrections to the hyperon vector coupling $f_1(0)$ in covariant baryon chiral perturbation theory Authors: L.S. Geng, J. Martin Camalich, and M.J. Vicente Vacas Categories: hep-ph Comments: 13 pages, 5 figures \\ We calculate the SU(3)-breaking corrections to the hyperon vector coupling $f_1(0)$ up to $\mathcal{O}(p^4)$ in covariant baryon chiral perturbation theory with dynamical octet and decuplet contributions. We find that the decuplet contributions are of similar or even larger size than the octet ones. Combining both, we predict positive SU(3)-breaking corrections to all the four independent $f_1(0)$'s (assuming isospin symmetry), which are consistent, within uncertainties, with the latest results form large $N_c$ fits, chiral quark models, and quenched lattice QCD calculations. \\ ( http://arxiv.org/abs/0903.4869 , 87kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:0812.0792 (*cross-listing*) Date: Wed, 3 Dec 2008 20:11:42 GMT (1205kb) Title: Holography and Thermodynamics of 5D Dilaton-gravity Authors: U.

Such theories are holographically very close to pure Yang-Mills theory in four dimensions. The existence and uniqueness of black-hole solutions is shown. It is also shown that a Hawking-Page transition exists at finite temperature if and only if the potential corresponds to a confining theory. The physics of the transition matches in detail with that of deconfinement of the Yang-Mills theory. The high-temperature phase asymptotes to a free gluon gas at high temperature matching the expected behavior from asymptotic freedom. The thermal gluon condensate is calculated and shown to be crucial for the existence of a non-trivial deconfining transition. The condensate of the topological charge is shown to vanish in the deconfined phase. \\ ( http://arxiv.org/abs/0812.0792 , 1205kb) ------------------------------------------------------------------------------ \\ arXiv:0903.2859 (*cross-listing*) Date: Mon, 16 Mar 2009 21:11:24 GMT (788kb) Title: Improved Holographic Yang-Mills at Finite Temperature: Comparison with Data Authors: U.

After fitting two phenomenological parameters in the potential, the model can reproduce in detail all thermodynamic functions at finite temperature. It also reproduces in detail all known spin-0 and spin-2 glueball observables at zero temperature and predicts the rest of the 0++ and 2++ towers. A similar two parameter fit in the CP-odd sector postdicts the correct second 0+- glueball mass, and predicts the rest of the 0+- tower. \\ ( http://arxiv.org/abs/0903.2859 , 788kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4379 (*cross-listing*) Date: Wed, 25 Mar 2009 17:53:34 GMT (149kb) Title: Equation of state and QCD transition at finite temperature Authors: A.

Vranas Categories: hep-lat hep-ph nucl-th Comments: 31 pages, 24 EPS-figures Report-no: CU-TP-1189 \\ We calculate the equation of state in 2+1 flavor QCD at finite temperature with physical strange quark mass and almost physical light quark masses using lattices with temporal extent Nt=8. Calculations have been performed with two different improved staggered fermion actions, the asqtad and p4 actions. Overall, we find good agreement between results obtained with these two O(a^2) improved staggered fermion discretization schemes. A comparison with earlier calculations on coarser lattices is performed to quantify systematic errors in current studies of the equation of state. We also present results for observables that are sensitive to deconfining and chiral aspects of the QCD transition on Nt=6 and 8 lattices. We find that deconfinement and chiral symmetry restoration happen in the same narrow temperature interval. In an Appendix we present a simple parametrization of the equation of state that can easily be used in hydrodynamic model calculations. In this parametrization we also incorporated an estimate of current uncertainties in the lattice calculations which arise from cutoff and quark mass effects. We estimate these systematic effects to be about 10 MeV \\ ( http://arxiv.org/abs/0903.4379 , 149kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4421 (*cross-listing*) Date: Wed, 25 Mar 2009 18:50:48 GMT (1140kb) Title: Worldline Monte Carlo for fermion models at large N_f Authors: Gerald Dunne, Holger Gies, Klaus Klingmuller, Kurt Langfeld Categories: hep-th hep-lat hep-ph Comments: 40 pages, 13 figures \\ Strongly-coupled fermionic systems can support a variety of low-energy phenomena, giving rise to collective condensation, symmetry breaking and a rich phase structure. We explore the potential of worldline Monte Carlo methods for analyzing the effective action of fermionic systems at large flavor number N_f, using the Gross-Neveu model as an example. Since the worldline Monte Carlo approach does not require a discretized spacetime, fermion doubling problems are absent, and chiral symmetry can manifestly be maintained. As a particular advantage, fluctuations in general inhomogeneous condensates can conveniently be dealt with analytically or numerically, while the renormalization can always be uniquely performed analytically. We also critically examine the limitations of a straightforward implementation of the algorithms, identifying potential convergence problems in the presence of fermionic zero modes as well as in the high-density region. \\ ( http://arxiv.org/abs/0903.4421 , 1140kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4436 (*cross-listing*) Date: Wed, 25 Mar 2009 19:22:17 GMT (34kb) Title: Effects of Bulk Viscosity at Freezeout Authors: Akihiko Monnai, Tetsufumi Hirano Categories: nucl-th hep-ph nucl-ex Comments: 11 pages, 11 figures \\ We investigate particle spectra and elliptic flow coefficients in relativistic heavy ion collisions by taking into account the distortion of phase space distributions due to bulk viscosity at freezeout. We first calculate the distortion of phase space distributions in a multi-component system within the Grad's fourteen moment method. We find some subtle issues when one matches macroscopic variables with microscopic momentum distributions in a multi-component system and develop a consistent procedure to uniquely determine the corrections in the phase space distributions. Next, we calculate particle spectra by using the Cooper-Frye formula to see the effect of the bulk viscosity. In spite of the relative smallness of the bulk viscosity, we find that it is likely to have a visible effect in particle spectra and elliptic flow coefficients. This indicates the importance of bulk viscosity together with shear viscosity if one wants to constrain the transport coefficients with better accuracy from experimental data. \\ ( http://arxiv.org/abs/0903.4436 , 34kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4588 (*cross-listing*) Date: Thu, 26 Mar 2009 13:58:10 GMT (3584kb) Title: The distribution of the dark matter in galaxies as the imprint of its Nature Authors: Christiane Frigerio Martins Categories: astro-ph.CO astro-ph.GA gr-qc hep-ph Comments: PhD thesis (Advisor: Paolo Salucci), 142 pages \\ The standard framework within which cosmological measurements are confronted and interpreted nowadays, called Lambda Cold Dark Matter, presents a Universe dominated by unknown forms of energy and matter. My Thesis is devoted to investigate the distribution of dark matter in galaxies and addresses the fact that the local universe-the small objects that orbit galaxies and the galaxy cores-turns out to be a marvelous laboratory for examining the nature of dark matter and the fundamental physics involved in structure formation and evolution. I develop tests, based on mass modeling of rotation curves, for the validation of dark matter models on galactic scales. These tests have been applied in analyzing the phenomenology of the cusp vs core controversy, and the phenomenon of non-Keplerian rotation curves as modification of the laws of gravity. I further investigate the properties and scaling laws of dark matter halos. My conclusion is that galactic observations provide strong imprints on the nature of dark matter. \\ ( http://arxiv.org/abs/0903.4588 , 3584kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4644 (*cross-listing*) Date: Thu, 26 Mar 2009 17:23:05 GMT (21kb) Title: Is There an Observable Limit to Lorentz Invariance at the Compton Wavelength Scale? Authors: Dinesh Singh, Nader Mobed Categories: hep-th gr-qc hep-ph Comments: 6 pages, 1 figure; Submission for the 2009 Gravity Research Foundation Essay Competition \\ The possibility of a frame-induced violation of Lorentz invariance due to non-inertial spin-1/2 particle motion is explored in detail for muon decay while in orbit near the event horizon of a microscopic Kerr black hole. It is explicitly shown that kinematic and curvature contributions to the muon's decay spectrum--in the absence of any unforeseen processes due to quantum gravity--lead to its stabilization at the muon's Compton wavelength scale. This example is emblematic of the search for unambiguous indicators to critically assess current and future approaches to quantum gravity research. \\ ( http://arxiv.org/abs/0903.4644 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:0903.4672 (*cross-listing*) Date: Thu, 26 Mar 2009 18:55:16 GMT (45kb) Title: The electromagnetic dark sector Authors: Jose Beltran Jimenez, Antonio L. Maroto Categories: astro-ph.CO gr-qc hep-ph hep-th Comments: 4 pages, 1 figure \\ We study the quantization of electromagnetism in an expanding universe. We find that the covariant quantization method exhibits certain difficulties when trying to impose the quantum Lorenz condition on cosmological scales. We thus consider the possibility of consistently quantizing without imposing such a condition. In this case there are three physical states, which are the two transverse polarizations of the massless photon and a new massless scalar mode coming from the temporal and longitudinal components of the electromagnetic field. Eliminating the residual gauge mode ensures the positivity of the energy density and the absence of negative norm states. The new state is decoupled from the conserved electromagnetic currents, but is non-conformally coupled to gravity and therefore can be excited from vacuum fluctuations by the expanding background. The cosmological evolution ensures that the new state modifies Maxwell's equations in a totally negligible way on sub-Hubble scales. However, on cosmological scales it can give rise to a non-negligible energy density which could explain in a natural way the present phase of accelerated expansion of the universe. \\ ( http://arxiv.org/abs/0903.4672 , 45kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:0805.4764 replaced with revised version Fri, 27 Mar 2009 03:44:19 GMT (9kb) Title: D and D_s in mass loaded flux tube Authors: Hong-Yun Shan and Ailin Zhang Categories: hep-ph hep-ex Comments: 5 pages, 2 tables, RevTex, some references added and some typos corrected \\ ( http://arxiv.org/abs/0805.4764 , 9kb) ------------------------------------------------------------------------------ \\ arXiv:0806.1235 replaced with revised version Fri, 27 Mar 2009 16:47:57 GMT (44kb,D) Title: Strong Conformal Dynamics at the LHC and on the Lattice Authors: Markus A.
