We show that the UV behaviour of the transverse gauge field polarizations can be improved by the Lifshitz operators, while the longitudinal polarizations get strongly coupled at energies lower than the ones in ordinary 5D theories, spoiling the usefulness of the construction in non-abelian gauge theories. We conclude that the improved behaviour as effective theories of the ordinary 5D models is not only related to locality and 5D gauge symmetries, but is a special property of the standard theories defined by the lowest dimensional operators. \\ ( http://arxiv.org/abs/1205.6207 , 19kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6212 Date: Mon, 28 May 2012 20:19:03 GMT (23kb) Title: Kinematical Test of Large Extra Dimension in Beta Decay Experiments Authors: Victor S. Basto-Gonzalez, Arman Esmaili and Orlando L. G. Peres Categories: hep-ph hep-ex Comments: 4 pages, 4 figures \\ The forthcoming experiments on neutrino mass measurement using beta decay, open a new window to explore the Large Extra Dimension model. The Kaluza-Klein tower of neutrinos in Large Extra Dimension contribute to the Kurie function of beta decay that can be tested kinematically. In addition to providing an alternative approach using just the kinematical properties, we show that KATRIN can probe the compactification radius of extra dimensions down to 0.2 \mu m which is better, at least by a factor of two, than the upper limits from neutrino oscillation experiments. \\ ( http://arxiv.org/abs/1205.6212 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6231 Date: Mon, 28 May 2012 22:55:03 GMT (54kb) Title: Quantum field theoretic approach to neutrino oscillations in matter Authors: Evgeny Kh. Akhmedov and Alina Wilhelm Categories: hep-ph astro-ph.SR hep-ex Comments: LaTeX, 38 pages, 1 figure \\ We consider neutrino oscillations in non-uniform matter in a quantum field theoretic (QFT) approach, in which neutrino production, propagation and detection are considered as a single process. We find the conditions under which the oscillation probability can be sensibly defined and demonstrate how the properly normalized oscillation probability can be obtained in the QFT framework. We derive the evolution equation for the oscillation amplitude and discuss the conditions under which it reduces to the standard Schr\"odinger-like evolution equation. It is shown that, contrary to the common usage, the Schr\"odinger-like evolution equation is not applicable in certain cases, such as oscillations of neutrinos produced in decays of free pions provided that sterile neutrinos with $\Delta m^2\gtrsim 1$ eV$^2$ exist. \\ ( http://arxiv.org/abs/1205.6231 , 54kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6232 Date: Mon, 28 May 2012 23:13:10 GMT (516kb) Title: Yukawa unification in SUSY SO(10) in light of the LHC Higgs data Authors: Marcin Badziak Categories: hep-ph Comments: 17 pages, 3 figures, invited brief review to appear in MPLA Report-no: Cavendish-HEP-12/10; DAMTP-2012-41 \\ The status of top-bottom-tau Yukawa coupling unification in supersymmetric SO(10) models is reviewed with a particular emphasis on the implications of the Higgs boson mass in the vicinity of 125 GeV, as suggested by the LHC Higgs data. In addition, the recently proposed model with negative \mu, D-term splitting of the soft scalar masses and non-universal gaugino masses generated by a non-zero F-term in a 24-dimensional representation of SU(5) \subset SO(10) is re-analysed in the context of the 125 GeV Higgs. The condition of top-bottom-tau Yukawa unification together with the Higgs mass of about 125 GeV impose strong lower mass limits on SUSY particles. Nevertheless, some of the MSSM particles may be within the reach of the LHC. In the case of models with positive \mu this is the gluino. While in the case of negative \mu these are the pseudoscalar Higgs, the lighter sbottom (sometimes strongly degenerate with the LSP leading to sbottom coannihilations), the right-handed down squark and the gluino. \\ ( http://arxiv.org/abs/1205.6232 , 516kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6260 Date: Tue, 29 May 2012 04:25:23 GMT (281kb,D) Title: How do you know if you ran through a wall? Authors: M. Pospelov, S. Pustelny, M. P. Ledbetter, D. F. Jackson Kimball, W. Gawlik, D. Budker Categories: hep-ph astro-ph.CO physics.atom-ph Comments: 5 pages, 1 figure \\ Stable domain walls of light (pseudo)scalar fields permeating the entire Universe and persisting to the present epoch is a generic consequence of many extensions to the Standard Model. Currently the combination of gravitational and cosmological constraints provides the best limits on such a possibility. We show that if domain walls are generated by an axion-like field with a coupling to the spins of standard-model particles, and the galactic environment contains a network of such walls, terrestrial experiments aimed at detection of wall-crossing events are realistic. In particular, a geographically separated but time-synchronized network of sensitive atomic magnetometers can detect a wall crossing and probe a range of model parameters currently unconstrained by astrophysical observations and gravitational experiments. \\ ( http://arxiv.org/abs/1205.6260 , 281kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6320 Date: Tue, 29 May 2012 10:15:45 GMT (6kb) Title: Mixing angle of doubly heavy baryons in QCD Authors: T.

A magnetized far detector allows for the wrong-sign muon appearance physics of electron-neutrino to muon-neutrino. This channel is the CPT of the LSND anomaly and provides 10 sigma sensitivity to the anomaly.

The results for S- and P-wave transversity amplitudes from the Analysis I are used in a model independent determination of helicity amplitudes. All three analyses provide similar evidence for rho^0(770)-f_0(980) mixing in S- and P-wave amplitudes. In Analyses I and II the S-wave amplitudes |S_d|^2 peak at rho^0(770) mass while the P-wave amplitudes |L_d|^2 dip at f_0(980) mass. In both analyses the S-wave amplitudes S_tau are nearly in phase with amplitudes L_tau for both transversitities tau=u(spin up) and d(spin down), indicating resonant phases of rho^0(770) also in the S-wave. The S-wave single flip amplitudes |S_1|^2 and the relative phases Phi(S_1)-Phi(L_1) show the same pattern. While the non-flip amplitudes |L_0|^2 are small below 960 MeV, there is a sudden rise above this mass that may reflect the presence of f_0(980) resonance. We show that the apparent dependence of rho^0(770) width on helicity in amplitudes |U_tau|^2 and |N_tau|^2 results from the interference of amplitudes with helicities lambda=+/-1 and not from the violation of rotational/Lorentz symmetry. This suggests that the production mechanism and the mechanism responsible for rho^0(770)-f_0(980) mixing have independent dynamical origins. \\ ( http://arxiv.org/abs/1205.6381 , 80kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6382 Date: Tue, 29 May 2012 15:02:04 GMT (397kb,D) Title: A variation of the charged particle spectrum shape as function of rapidity in high energy pp collisions Authors: A.

Indeed, the contributions of the light right-handed sneutrinos from the inverse seesaw significantly enhance the Higgs-mediated penguin diagrams. We find that this can increase the different branching ratios by as much as two orders of magnitude. \\ ( http://arxiv.org/abs/1205.6400 , 182kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6416 Date: Tue, 29 May 2012 16:42:46 GMT (711kb) Title: Dark Matter and Higgs Boson in a Model with Discrete Gauge Symmetry Authors: Cheng-Wei Chiang, Takaaki Nomura, Jusak Tandean Categories: hep-ph Comments: 5 pages, 4 figures \\ In view of ongoing hunts for the Higgs boson at the LHC and direct searches of dark matter, we explore the possibility of accommodating the potential results in a simple new physics model with discrete gauge symmetry as well as light neutrino masses.

Following the same approach we calculate in the minimal composite Higgs model (MCHM) the Higgs mass as a function of the fermionic resonance masses. The simplicity of the method allows us to study several versions of the MCHM and show that a Higgs with a mass around 125 GeV requires, quite generically, fermionic resonances below the TeV, and therefore accessible at the LHC. We also examine the couplings of the Higgs to the SM fermions and calculate their deviation from the SM value. \\ ( http://arxiv.org/abs/1205.6434 , 157kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6462 Date: Tue, 29 May 2012 19:39:58 GMT (67kb) Title: Parton energy loss in glasma Authors: P.

Warringa Categories: hep-th hep-ph Comments: 13 pages, 7 figures, revtex \\ We investigate the real-time dynamics of the chiral magnetic effect in quantum electrodynamics (QED) and quantum chromodynamics (QCD). We consider a field configuration of parallel (chromo)electric and (chromo)magnetic fields with a weak perpendicular electromagnetic magnetic field. The chiral magnetic effect induces an electromagnetic current along this perpendicular magnetic field, which we will compute using linear response theory. We discuss specific results for a homogeneous sudden switch-on and a pulsed (chromo)electric field in a static and homogeneous (chromo)magnetic field. Our methodology can be easily extended to more general situations. The results are useful for investigating the chiral magnetic effect with heavy ion collisions and with lasers that create strong electromagnetic fields. As a side result we obtain the rate of chirality production for massive fermions in parallel electric and magnetic fields that are static and homogeneous. \\ ( http://arxiv.org/abs/1205.5679 , 141kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6076 (*cross-listing*) Date: Mon, 28 May 2012 10:58:11 GMT (637kb) Title: Lattice study of infrared behaviour in SU(3) gauge theory with twelve massless flavours Authors: C.-J. David Lin, Kenji Ogawa, Hiroshi Ohki, Eigo Shintani Categories: hep-lat hep-ph Comments: 28 pages, 14 figures, 4 tables \\ We present details of a lattice study of infrared behaviour in SU(3) gauge theory with twelve massless fermions in the fundamental representation. Using the step-scaling method, we compute the coupling constant in this theory over a large range of scale. The renormalisation scheme in this work is defined by the ratio of Polyakov loops in the directions with different boundary conditions. We closely examine systematic effects, and find that they are dominated by errors arising from the continuum extrapolation. Our investigation suggests that SU(3) gauge theory with twelves flavours contains an infrared fixed point, although some of the continuum-extrapolation procedures lead to weaker evidence for the existence of this fixed point. \\ ( http://arxiv.org/abs/1205.6076 , 637kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6205 (*cross-listing*) Date: Mon, 28 May 2012 20:00:05 GMT (41kb,D) Title: The holographic quantum effective potential at finite temperature and density Authors: Elias Kiritsis and Vasilis Niarchos Categories: hep-th cond-mat.str-el gr-qc hep-ph Comments: 27 pages Report-no: CCTP-2012-12 \\ We develop a formalism that allows the computation of the quantum effective potential of a scalar order parameter in a class of holographic theories at finite temperature and charge density.

Mota, Sigbj{\o}rn Hervik Categories: hep-th astro-ph.CO gr-qc hep-ph Comments: 47 pages, 3 figures \\ Motivated by the couplings of the dilaton in four-dimensional effective actions, we investigate the cosmological consequences of a scalar field coupled both to matter and a Maxwell-type vector field. The vector field has a background isotropy-violating component. New anisotropic scaling solutions which can be responsible for the matter and dark energy dominated epochs are identified and explored. For a large parameter region the universe expands almost isotropically. Using that the CMB quadrupole is extremely sensitive to shear, we constrain the ratio of the matter coupling to the vector coupling to be less than 10^(-5). Moreover, we identify a large parameter region, corresponding to a strong vector coupling regime, yielding exciting and viable cosmologies close to the LCDM limit. \\ ( http://arxiv.org/abs/1205.6261 , 3248kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6267 (*cross-listing*) Date: Tue, 29 May 2012 05:03:10 GMT (18kb) Title: Holomorphic Bisectional Curvatures, Supersymmetry Breaking, and Affleck-Dine Baryogenesis Authors: Bhaskar Dutta, Kuver Sinha Categories: hep-th hep-ph Comments: 9 pages \\ Working in $D=4, N=1$ supergravity, we utilize relations between holomorphic sectional and bisectional curvatures of Kahler manifolds to constrain Affleck-Dine baryogenesis. We show the following No-Go result: Affleck-Dine baryogenesis cannot be performed if the holomorphic sectional curvature at the origin is isotropic in tangent space; as a special case, this rules out spaces of constant holomorphic sectional curvature (defined in the above sense) and in particular maximally symmetric coset spaces. We also investigate scenarios where inflationary supersymmetry breaking is identified with the supersymmetry breaking responsible for mass splitting in the visible sector, using conditions of sequestering to constrain manifolds where inflation can be performed. \\ ( http://arxiv.org/abs/1205.6267 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6284 (*cross-listing*) Date: Tue, 29 May 2012 07:39:19 GMT (3611kb) Title: Core-Collapse Supernovae as Supercomputing Science: a status report toward 6D simulations with exact Boltzmann neutrino transport in full general relativity Authors: Kei Kotake, Kohsuke Sumiyoshi, Shoichi Yamada, Tomoya Takiwaki, Takami Kuroda, Yudai Suwa, and Hiroki Nagakura Categories: astro-ph.HE gr-qc hep-ph nucl-th Comments: 40 pages, 21 figures, submitted to Progress of Theoretical and Experimental Physics \\ This is a status report on our endeavor to reveal the mechanism of core-collapse supernovae (CCSNe) by large-scale numerical simulations. Multi-dimensionality of the supernova engine, general relativisitic magnetohydrodynamics, energy and lepton number transport by neutrinos emitted from the forming neutron star as well as nuclear interactions there, are all believed to play crucial roles in repelling infalling matter and producing energetic explosions. These ingredients are nonlinearly coupled with one another in the dynamics of core-collapse, bounce, and shock expansion. Serious quantitative studies of CCSNe hence make extensive numerical computations mandatory. Since neutrinos are neither in thermal nor in chemical equilibrium in general, their distributions in the phase space should be computed. This is a six dimensional (6D) neutrino transport problem and quite a challenge even for those with an access to the most advanced numerical resources such as the "K computer". To tackle this problem, we have embarked on multi-front efforts. In particular we report in this paper our recent progresses in the treatments of multi-dimensional (multi-D) radiation-hydrodynamics. We are currently proceeding on two different paths to the ultimate goal; in one approach we employ an approximate but highly efficient scheme for neutrino transport and treat 3D hydrodynamics and/or general relativity rigorously; some neutrino-driven explosions will be presented and comparisons will be made between 2D and 3D models quantitatively; in the second approach, on the other hand, exact but so far Newtonian Boltzmann equations are solved in two and three spatial dimensions; we will show some demonstrative test simulations. We will also address the perspectives of exa-scale computations on the next generation supercomputers. \\ ( http://arxiv.org/abs/1205.6284 , 3611kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6292 (*cross-listing*) Date: Tue, 29 May 2012 08:14:00 GMT (2539kb,D) Title: Diffuse supernova neutrinos: oscillation effects, stellar cooling and progenitor mass dependence Authors: Cecilia Lunardini and Irene Tamborra Categories: astro-ph.SR hep-ex hep-ph Comments: 17 pages, including 4 figures and 1 table \\ We estimate the diffuse supernova neutrino background (DSNB) using, for the first time, the most recent progenitor-dependent, long-term supernova simulations and including neutrino oscillations for several post-bounce times. Assuming multi-angle matter suppression of collective effects during the accretion phase, we find that oscillation effects are dominated by the matter-driven MSW resonances, while neutrino-neutrino collective effects contribute at the 5-10% level. The impact of the neutrino mass hierarchy, of the time-dependent neutrino spectra and of the diverse progenitor star population is 10% or less, small compared to the uncertainty of at least 25% of the normalization of the supernova rate. Therefore, assuming that the sign of the neutrino mass hierarchy will be determined within the next decade, the future detection of the DSNB will deliver approximate information on the MSW-oscillated neutrino spectra. With a reliable model for neutrino emission, its detection will be a powerful instrument to provide complementary information on the star formation rate and for learning about stellar physics. \\ ( http://arxiv.org/abs/1205.6292 , 2539kb) ------------------------------------------------------------------------------ \\ arXiv:1205.6410 (*cross-listing*) Date: Tue, 29 May 2012 16:24:08 GMT (21kb) Title: A Lattice Study of the Glue in the Nucleon Authors: R.

It is usually assumed that those axionlike particles (ALPs) could produce a drop in the energy spectra of gamma ray sources and possibly decrease the opacity of the Universe for TeV gamma rays. We show here that these assumptions are in fact based on an average behavior that cannot happen in real observations of single sources. We propose a new method to search for photon-ALP oscillations, taking advantage of the fact that a single observation would deviate from the average expectation. Our method is based on the search for irregularities in the energy spectra of gamma ray sources. We predict features that are unlikely to be produced by known astrophysical processes and a new signature of ALPs that is easily falsifiable. \\ ( http://arxiv.org/abs/1205.6428 , 38kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1105.0756 replaced with revised version Tue, 29 May 2012 02:44:18 GMT (296kb) Title: Top quark pair production via $e^{+}e^{-}$ collision in the littlest Higgs model with T-parity at the ILC Authors: Bingfang Yang, Jinzhong Han, Lin Wang and Xuelei Wang Categories: hep-ph Journal-ref: Phys.Rev.D83:094020,2011 DOI: 10.1103/PhysRevD.83.094020 \\ ( http://arxiv.org/abs/1105.0756 , 296kb) ------------------------------------------------------------------------------ \\ arXiv:1109.0426 replaced with revised version Tue, 29 May 2012 08:46:37 GMT (757kb) Title: Complex 2D Matrix Model and Geometrical Map on Complex-Nc Plane Authors: Kanabu Nawa, Sho Ozaki, Hideko Nagahiro, Daisuke Jido, Atsushi Hosaka Categories: hep-ph hep-th Comments: 6 pages, 4 figures, v2: presentation improved, FIG.1 added Report-no: YITP-11-82 \\ ( http://arxiv.org/abs/1109.0426 , 757kb) ------------------------------------------------------------------------------ \\ arXiv:1109.2079 replaced with revised version Tue, 29 May 2012 00:43:03 GMT (22kb) Title: Studies in Small Field Inflation Authors: Michael Dine, Lawrence Pack Categories: hep-ph hep-th Comments: 16 pages. issues with single field inflation identified and clarified; role of discrete R symmetries clarified; error in discussion of a non-hybrid model corrected \\ ( http://arxiv.org/abs/1109.2079 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:1112.5339 replaced with revised version Tue, 29 May 2012 11:43:55 GMT (113kb) Title: RG running in a minimal UED model in light of recent LHC Higgs mass bounds Authors: Mattias Blennow, Henrik Melbeus, Tommy Ohlsson, He Zhang Categories: hep-ph hep-ex Comments: 16 pages, 6 figures, RevTeX4.
