Sloth Categories: hep-th astro-ph.CO hep-ph Comments: 35 pages, 4 figures \\ We investigate radiative corrections to the inflaton potential from heavy fields undergoing a fast-roll phase transition. We find that a logarithmic one-loop correction to the inflaton potential involving this field can induce a temporary running of the spectral index. The induced running can be a short burst of strong running, which may be related to the observed anomalies on large scales in the cosmic microwave spectrum, or extend over many e-folds, sustaining an effectively constant running to be searched for in the future. We implement this in a general class of models, where effects are mediated through a heavy messenger field sitting in its minimum. Interestingly, within the present framework it is a generic outcome that a large running implies a small field model with a vanishing tensor-to-scalar ratio, circumventing the normal expectation that small field models typically lead to an unobservable small running of the spectral index. An observable level of tensor modes can also be accommodated, but, surprisingly, this requires running to be induced by a curvaton. If upcoming observations are consistent with a small tensor-to-scalar ratio as predicted by small field models of inflation, then the present study serves as an explicit example contrary to the general expectation that the running will be unobservable. \\ ( http://arxiv.org/abs/1501.06919 , 178kb) ------------------------------------------------------------------------------ \\ arXiv:1501.06938 Date: Tue, 27 Jan 2015 21:42:14 GMT (779kb,D) Title: Dyonic Stars for Holography Authors: Daniel Carney, Mohammad Edalati Categories: hep-th Comments: 10+4 pages \\ We construct back-reacted asymptotically AdS_4 backgrounds with both electric and magnetic charge, at finite temperature and chemical potential. The system consists of a condensed bulk Dirac field hovering over a charged black brane. We give a detailed microscopic treatment of the bulk fermions, from which we derive the usual fluid approximations describing the condensate. In the context of holography, such a gravitational solution is dual to a (2+1)-dimensional CFT with a U(1) current, at finite density and strong coupling, subjected to a transverse magnetic field. \\ ( http://arxiv.org/abs/1501.06938 , 779kb) ------------------------------------------------------------------------------ \\ arXiv:1501.06977 Date: Wed, 28 Jan 2015 02:35:22 GMT (22kb,D) Title: Euclidean quantum M5 brane theory on $S^1 \times S^5$ Authors: Andreas Gustavsson Categories: hep-th Comments: 31 pages \\ We consider Euclidean quantum M5 brane theory on $S^1\times S^5$. Dimensional reduction along $S^1$ gives a 5d SYM on $S^5$. We derive this 5d SYM theory from a classical Lorentzian M5 brane Lagrangian on $S^1 \times S^5$, where $S^1$ is a timelike circle of radius $T$, by performing a Scherk-Schwarz reduction along $S^1$ followed by Wick rotation of $T$. \\ ( http://arxiv.org/abs/1501.06977 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:1501.06998 Date: Wed, 28 Jan 2015 06:20:56 GMT (2312kb) Title: p-wave Holographic Superconductors from Born-Infeld Black Holes Authors: Pankaj Chaturvedi and Gautam Sengupta Categories: hep-th Comments: 26 pages, 18 figures \\ We obtain (2+1) dimensional p-wave holographic superconductors from charged Born-Infeld black holes in the presence of massive charged vector fields in a bulk $AdS_4$ Einstein-Born-Infeld theory through the $AdS_4$-$CFT_3$ correspondence. Below a certain critical transition temperature the charged black hole develops vector hair that corresponds to charged vector condensate in the strongly coupled (2+1) dimensional boundary field theory that breaks both the $U(1)$ symmetry as well as the rotational invariance. The holographic free energy is computed for the boundary field theory which shows that the vector order parameter exhibits a rich phase structure involving zeroth order, first order, second order and retrograde phase transitions for different values of the backreaction and the Born-Infeld parameters. We numerically compute the ac conductivity for the p-wave superconducting phase of the strongly coupled (2+1) dimensional boundary field theory which also depends on the relative values of the parameters in the theory. \\ ( http://arxiv.org/abs/1501.06998 , 2312kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07014 Date: Wed, 28 Jan 2015 07:54:32 GMT (62kb) Title: Adler-Bardeen theorem and cancellation of gauge anomalies to all orders in nonrenormalizable theories Authors: Damiano Anselmi Categories: hep-th hep-ph math-ph math.MP Comments: 63 pages \\ We prove the Adler-Bardeen theorem in a large class of general gauge theories, including nonrenormalizable ones. We assume that the gauge symmetries are general covariance, local Lorentz symmetry and Abelian and non-Abelian Yang-Mills symmetries, and that the local functionals of vanishing ghost number satisfy a variant of the Kluberg-Stern--Zuber conjecture. We show that if the gauge anomalies are trivial at one loop, for every truncation of the theory there exists a subtraction scheme where they manifestly vanish to all orders, within the truncation. Outside the truncation the cancellation of gauge anomalies can be enforced by fine-tuning local counterterms. The framework of the proof is worked out by combining a recently formulated chiral dimensional regularization with a gauge invariant higher-derivative regularization. If the higher-derivative regularizing terms are placed well beyond the truncation, and the energy scale $\Lambda$ associated with them is kept fixed, the theory is super-renormalizable and has the property that, once the gauge anomalies are cancelled at one loop, they manifestly vanish from two loops onwards by simple power counting. When the $\Lambda$ divergences are subtracted away and $\Lambda$ is sent to infinity, the anomaly cancellation survives in a manifest form within the truncation and in a nonmanifest form outside. The standard model coupled to quantum gravity satisfies all the assumptions, so it is free of gauge anomalies to all orders. \\ ( http://arxiv.org/abs/1501.07014 , 62kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07038 Date: Wed, 28 Jan 2015 09:20:23 GMT (439kb,D) Title: Non-Abelian Sine-Gordon Solitons: Correspondence between $SU(N)$ Skyrmions and ${\mathbb C}P^{N-1}$ Lumps Authors: Minoru Eto, Muneto Nitta Categories: hep-th hep-ph Comments: 24 pages, 4 figures \\ Topologically stable non-Abelian sine-Gordon solitons have been found recently in the $U(N)$ chiral Lagrangian and a $U(N)$ gauge theory with two $N$ by $N$ complex scalar fields coupled to each other. We construct the effective theory on a non-Abelian sine-Gordon soliton that is a nonlinear sigma model with the target space ${\mathbb R} \times {\mathbb C}P^{N-1}$. We then show that ${\mathbb C}P^{N-1}$ lumps on it represent $SU(N)$ Skyrmions in the bulk point of view, providing a physical realization of the rational map Ansatz for Skyrmions of the translational (Donaldson) type. We find therefore that Skyrmions can exist stably without the Skyrme term. \\ ( http://arxiv.org/abs/1501.07038 , 439kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07144 Date: Wed, 28 Jan 2015 15:24:17 GMT (15kb) Title: On The Pauli-Weisskopf Anti-Dirac Paper Authors: Walter Dittrich Categories: hep-th quant-ph \\ We review in this article the role which the work of Pauli and Weisskopf played in formulating a quantum field theory of spinless particles. To make our computations as transparent as possible, we offer a physicist's derivation of the Klein-Gordon-Fock equation. Since invariant functions play a significant part in our paper, we will discuss them in great detail. We emphasize Pauli's and Weisskopf's view that Dirac's hole theory is totally obsolete in formulating a consistent quantum field theory, be it for scalar or spinor particles. As an important example we present the calculation for producing charged scalar particles in an external electric field. \\ ( http://arxiv.org/abs/1501.07144 , 15kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07147 Date: Wed, 28 Jan 2015 15:29:08 GMT (78kb) Title: Some remarks on the use of effective Lagrangians in QED and QCD Authors: Walter Dittrich Categories: hep-th \\ We discuss in this article the usefulness of the effective Lagrangians (L_eff) of QED and QCD within the one-loop approximation. Instead of calculating L_eff via complicated computations with Schwinger's proper-time technique or Feynman graphs, we prefer to employ the energy-momentum tensor and the leading-log model. The advantage is that we do not have to demand the external electromagnetic or color field to be constant. There are also some critical remarks added which cast doubt on the use of LQCD with covariant constant fields in explaining the nature of the QCD vacuum. \\ ( http://arxiv.org/abs/1501.07147 , 78kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07160 Date: Mon, 26 Jan 2015 21:00:12 GMT (25kb) Title: Effective Field Theory of Broken Spatial Diffeomorphisms Authors: Chunshan Lin, Lance Z. Labun Categories: hep-th gr-qc Comments: 16 pages \\ We study the low energy effective theory describing gravity with broken spatial diffeomorphism invariance. In the unitary gauge, the Goldstone bosons associated with broken diffeomorphisms are eaten and the graviton becomes a massive spin-2 particle with 5 well-behaved degrees of freedom. In this gauge, the most general theory is built with the lowest dimension operators invariant under only temporal diffeomorphisms. Imposing the additional shift and SO(3) internal symmetries, we analyze the perturbations on a FRW background. At linear perturbation level, the observables of this theory are characterized by six parameters, including the usual cosmological parameters and two additional coupling constants for the symmetry-breaking scalars. We discuss several examples relevant to theories of massive gravity. \\ ( http://arxiv.org/abs/1501.07160 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07236 Date: Wed, 28 Jan 2015 19:05:53 GMT (191kb,D) Title: Stringy Symmetries and the Higher Spin Square Authors: Matthias R Gaberdiel and Rajesh Gopakumar Categories: hep-th Comments: 23 pages, 1 figure \\ Tensionless string theory on AdS3 x S3 x T4, as captured by a free symmetric product orbifold, has a large set of conserved currents which can be usefully organised in terms of representations of a N=(4,4) supersymmetric higher spin algebra. In this paper we focus on the single particle currents which generate the asymptotic stringy symmetry algebra on AdS3, and whose wedge modes describe the unbroken gauge symmetries of string theory in this background. We show that this global subalgebra contains two distinct higher spin algebras that generate the full algebra as a `higher spin square'. The resulting unbroken stringy symmetry algebra is exponentially larger than the two individual higher spin algebras. \\ ( http://arxiv.org/abs/1501.07236 , 191kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07248 Date: Wed, 28 Jan 2015 19:21:55 GMT (18kb) Title: Dimensional oxidation and modular completion of non-geometric type IIB action Authors: Xin Gao and Pramod Shukla Categories: hep-th Comments: 19 pages \\ Utilizing a setup of type IIB superstring theory compactified on an orientifold of T^6/(Z2 x Z2), we propose a modular invariant dimensional oxidation of the four-dimensional scalar potential. In the oxidized ten-dimensional supergravity action, the standard NS-NS and RR three form fluxes (H-, F-) as well as the non-geometric fluxes (Q-, P-) are found to nicely rearrange themselves to form generalized flux-combinations. As an application towards moduli stabilization, using the same S-duality invariant scalar potential, we examine the recently proposed No-Go theorem (in arXiv:1409.7075) about creating a mass-hierarchy between universal-axion and the dilaton relevant for axionic-inflation. We find the No-Go arguments to be quite robust even with the inclusion of non-geometric (Q-, P-) fluxes. \\ ( http://arxiv.org/abs/1501.07248 , 18kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1501.06404 (*cross-listing*) Date: Mon, 26 Jan 2015 14:12:18 GMT (500kb,D) Title: Quantum Gravity and the Large Scale Anomaly Authors: Alexander Y.

The collider signatures of irrelevant operators are suppressed by the high-energy cutoff (torsion-field mass) $\Lambda$, and cannot be experimentally accessible at TeV scales. Whereas the dynamics of relevant operators accounts for (i) the SM symmetry-breaking in the domain of infrared-stable fixed point with the energy scale $v\approx 239.5$ GeV and (ii) composite Dirac particles restoring the SM symmetry in the domain of ultraviolate-stable fixed point with the energy scale ${\mathcal E}\gtrsim 5$ TeV. To search for the resonant phenomena of composite Dirac particles with peculiar kinematic distributions in final states, we discuss possible high-energy processes: multi-jets and dilepton Drell-Yan process in LHC $p\,p$ collisions, the resonant cross-section in $e^-e^+$ collisions annihilating to hadrons and deep inelastic lepton-hadron $e^-\,p$ scatterings. To search for the nonresonant phenomena due to the form-factor of Higgs boson, we calculate the variation of Higgs-boson production and decay rate with the CM energy in LHC. We also present the discussions on four-fermion operators in the lepton sector and the mass-squared differences for neutrino oscillations in short baseline experiments. \\ ( http://arxiv.org/abs/1501.06844 , 154kb) ------------------------------------------------------------------------------ \\ arXiv:1501.06918 (*cross-listing*) Date: Tue, 27 Jan 2015 21:00:22 GMT (69kb) Title: Cosmological scalar field perturbations can grow Authors: Miguel Alcubierre, Axel de la Macorra, Alberto Diez-Tejedor and Jos\'e M.

With the aid of this method, we explore the cosmic evolution of DBI field and quintessence with the potential of multiple vacua. Then we find that the scalars are always frozen in the false or true vacuum in the end. Compared to the evolution of quintessence, the DBI field has more times of oscillations around the vacuum of the potential. The reason for this point is that, with the increasing of speed $\dot{\phi}$, the friction term of DBI field is greatly decreased. Thus the DBI field acquires more times of oscillations. \\ ( http://arxiv.org/abs/1501.06960 , 59kb) ------------------------------------------------------------------------------ \\ arXiv:1501.06966 (*cross-listing*) Date: Wed, 28 Jan 2015 01:09:41 GMT (16kb) Title: An Almost Contact Structure on $G_2$-Manifolds Authors: Albert J.

Bazhanov and Sergey M. Sergeev Categories: math-ph hep-th math.MP Comments: 35 pages, 7 figures \\ For every quantized Lie algebra there exists a map from the tensor square of the algebra to itself, which by construction satisfies the set-theoretic Yang-Baxter equation. This map allows one to define an integrable discrete quantum evolution system on quadrilateral lattices, where local degrees of freedom (dynamical variables) take values in a tensor power of the quantized Lie algebra. The corresponding equations of motion admit the zero curvature representation. The commuting Integrals of Motion are defined in the standard way via the Quantum Inverse Problem Method, utilizing Baxter's famous commuting transfer matrix approach. All elements of the above construction have a meaningful quasi-classical limit. As a result one obtains an integrable discrete Hamiltonian evolution system, where the local equation of motion are determined by a classical Yang-Baxter map and the action functional is determined by the quasi-classical asymptotics of the universal R-matrix of the underlying quantum algebra. In this paper we present detailed considerations of the above scheme on the example of the algebra $U_q(sl(2))$ leading to discrete Liouville equations, however the approach is rather general and can be applied to any quantized Lie algebra. \\ ( http://arxiv.org/abs/1501.06984 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07027 (*cross-listing*) Date: Wed, 28 Jan 2015 08:36:47 GMT (29kb) Title: On the question of current conservation for the Two-Body Dirac equations of constraint theory Authors: Matthias Lienert Categories: quant-ph hep-th nucl-th Comments: 25 pages, no figures \\ The Two-Body Dirac equations of constraint theory are of special interest not only in view of applications for phenomenological calculations of mesonic spectra but also because they avoid no-go theorems about relativistic interactions. Furthermore, they provide a quantum mechanical description in a manifestly Lorentz invariant way using the concept of a multi-time wave function. In this paper, we place them into the context of the multi-time formalism of Dirac, Tomonaga and Schwinger for the first time. A general physical and mathematical framework is outlined and the mechanism which permits relativistic interaction is identified. The main requirement derived from the general framework is the existence of conserved tensor currents with a positive component which can play the role of a probability density. We analyze this question for a general class of Two-Body Dirac equations thoroughly and comprehensively. While the free Dirac current is not conserved, it is possible to find replacements. Improving on previous research, we achieve definite conclusions whether restrictions of the function space or of the interaction terms can guarantee the positive definiteness of the currents -- and whether such restrictions are physically adequate. The consequences of the results are drawn, with respect to both applied and foundational perspectives. \\ ( http://arxiv.org/abs/1501.07027 , 29kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07031 (*cross-listing*) Date: Wed, 28 Jan 2015 08:53:11 GMT (1319kb) Title: Disentangled topological numbers by a purification of entangled mixed states for non-interacting fermion systems Authors: T. Fukui and Y. Hatsugai Categories: cond-mat.mes-hall hep-th quant-ph Comments: 6 pages, 3 figures \\ We argue that the entanglement Chern number proposed recently is an invariant under the adiabatic deformation of a gapped many-body groundstate into {\it disentangled/purified} one, which means a partition of the Chern number (disentangled Chern number) into subsystems. We generalize the idea to another topological number, the Z$_2$ Berry phase for a system with particle-hole symmetry, and apply it to a groundstate in a weak topological phase where the Chern number is vanishing but it has, nevertheless, edge states. This entanglement Berry phase is especially useful for characterizing random systems with non trivial edge states. \\ ( http://arxiv.org/abs/1501.07031 , 1319kb) ------------------------------------------------------------------------------ \\ arXiv:1501.07150 (*cross-listing*) Date: Wed, 28 Jan 2015 15:36:05 GMT (619kb) Title: Yang-Mills two-point functions in linear covariant gauges Authors: A. C. Aguilar, D. Binosi and J. Papavassiliou Categories: hep-ph hep-lat hep-th Comments: 28 pages, 10 figures \\ In this work we use two different but complementary approaches in order to study the ghost propagator of a pure SU(3) Yang-Mills theory quantized in the linear covariant gauges, focusing on its dependence on the gauge-fixing parameter $\xi$ in the deep infrared. In particular, we first solve the Schwinger-Dyson equation that governs the dynamics of the ghost propagator, using a set of simplifying approximations, and under the crucial assumption that the gluon propagators for $\xi>0$ are infrared finite, as is the case in the Landau gauge $(\xi=0)$. Then we appeal to the Nielsen identities, and express the derivative of the ghost propagator with respect to $\xi$ in terms of certain auxiliary Green's functions, which are subsequently computed under the same assumptions as before. Within both formalisms we find that for $\xi>0$ the ghost dressing function approaches zero in the deep infrared, in sharp contrast to what happens in the Landau gauge, where it known to saturate at a finite (non-vanishing) value. The Nielsen identities are then extended to the case of the gluon propagator, and the $\xi$-dependence of the corresponding gluon masses is derived using as input the results obtained in the previous steps. The result turns out to be logarithmically divergent in the deep infrared; the compatibility of this behavior with the basic assumption of a finite gluon propagator is discussed, and a specific Ansatz is put forth, which readily reconciles both features. \\ ( http://arxiv.org/abs/1501.07150 , 619kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1312.3313 (*cross-listing*) replaced with revised version Wed, 28 Jan 2015 14:35:09 GMT (2509kb,D) Title: Planck Data Reconsidered Authors: David Spergel, Raphael Flauger, Renee Hlozek Categories: astro-ph.CO gr-qc hep-ph hep-th Comments: 15 pages, v2: clarifying comments added, typos corrected, priors for interfrequency calibration updated, published in PRD Journal-ref: Phys.Rev.D91:023518,2015 DOI: 10.1103/PhysRevD.91.023518 \\ ( http://arxiv.org/abs/1312.3313 , 2509kb) ------------------------------------------------------------------------------ \\ arXiv:1403.1055 (*cross-listing*) replaced with revised version Wed, 28 Jan 2015 17:05:45 GMT (116kb,D) Title: On supersymmetric Dirac delta interactions Authors: J.
