Pando Zayas and Cheng Peng Categories: hep-th Comments: 18 pages Report-no: MCTP-13-03, NSF-KITP-13-039 \\ We show explicitly how the exact renormalization group equation of interacting vector models in the large N limit can be mapped into certain higher-spin equations of motion. The equations of motion are generalized to incorporate a multiparticle extension of the higher-spin algebra, which reflects the "multitrace" nature of the interactions in the dual field theory from the holographic point of view. \\ ( http://arxiv.org/abs/1303.6641 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6685 Date: Tue, 26 Mar 2013 22:28:26 GMT (1954kb) Title: Brane SUSY Breaking and Inflation: Implications for Scalar Fields and CMB Distorsion Authors: A. Sagnotti (Scuola Normale Superiore and INFN, Pisa, ITALY) Categories: hep-th gr-qc hep-ex hep-ph Comments: 9 pages, 4 figures, talk presented at Rencontres de Moriond EW2013, La Thuile, March 2 - 9 2013 \\ I elaborate on a link between the string--scale breaking of supersymmetry that occurs in a class of superstring models and the onset of inflation. The link rests on spatially flat cosmologies supported by a scalar field driven by an exponential potential. If, as in String Theory, this potential is steep enough, under some assumptions that are spelled out in the text the scalar can only climb up as it emerges from an initial singularity. In the presence of another mild exponential, slow--roll inflation is thus injected during the ensuing descent and definite imprints are left in the CMB power spectrum: the quadrupole is systematically reduced and, depending on the choice of two parameters, an oscillatory behavior can also emerge for low multipoles l < 50, in qualitative agreement with WMAP9 and PLANCK data. \\ ( http://arxiv.org/abs/1303.6685 , 1954kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6726 Date: Wed, 27 Mar 2013 02:24:07 GMT (160kb,D) Title: Towards New Classes of Flux Compactifications Authors: Paul Franche Categories: hep-th Comments: 111 pages, 7 figures, PhD thesis \\ We derive novel solutions of flux compactification with D7-branes on the resolved conifold in type IIB String Theory and later extend this solution to allow for non-zero temperature. At zero temperature, we find that adding D7-branes via the Ouyang embedding contributes to the supersymmetry-breaking (1,2) imaginary-self-dual flux, without generating a bulk cosmological constant. We further find that having D7-branes and a resolved conifold together give rise to a non-trivial D-term on the D7-branes. This supersymmetry-breaking term vanishes when we take the singular conifold limit, although supersymmetry appears to remain broken. We also lift our construction to F-theory where we show that the type IIB (1,2) flux goes to (2,2) non-primitive flux on the fourfold. In the second part of the thesis, we extend these results by taking the non-extremal limit of our geometry to incorporate temperature. In this case, the internal NS-NS and R-R fluxes are no longer expected to be self-dual, but they should also naturally be extensions of the fluxes found above. From the supergravity equations of motion, we compute how the new contributions to the fluxes should enter, due to the squashing of the resolved metric and non-extremality. This provides us with a compelling gravity dual of large N thermal quantum chromodynamics with flavor. \\ ( http://arxiv.org/abs/1303.6726 , 160kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6727 Date: Wed, 27 Mar 2013 02:27:52 GMT (25kb) Title: The O_{D,D} Geometry of String Theory Authors: David S. Berman, Chris D. A. Blair, Emanuel Malek and Malcolm J. Perry Categories: hep-th Comments: 26 pages, latex \\ We construct an action for double field theory using a metric connection that is compatible with both the generalised metric and the O_{D,D} structure. The connection is simultaneously torsionful and flat. Using this connection one may construct a proper covariant derivative for double field theory. We then write the doubled action in terms of the generalised torsion of this connection. This action then exactly reproduces that required for doubled field theory and gauged supergravity. \\ ( http://arxiv.org/abs/1303.6727 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6732 Date: Wed, 27 Mar 2013 03:12:45 GMT (18kb) Title: Target duality in N=8 superconformal mechanics and the coupling of dual pairs Authors: Marcelo Gonzales, Sadi Khodaee, Olaf Lechtenfeld, Francesco Toppan Categories: hep-th math-ph math.MP Comments: 1+18 pages \\ We couple dual pairs of N=8 superconformal mechanics with conical targets of dimension d and 8-d. The superconformal coupling generates an oscillator-type potential on each of the two target factors, with a frequency depending on the respective dual coordinates. In the case of the inhomogeneous (3,8,5) model, which entails a monopole background, it is necessary to add an extra supermultiplet of constants for half of the supersymmetry. The N=4 analog, joining an inhomogeneous (1,4,3) with a (3,4,1) multiplet, is also analyzed in detail. \\ ( http://arxiv.org/abs/1303.6732 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6772 Date: Wed, 27 Mar 2013 09:31:47 GMT (497kb) Title: Renormalization of an SU(2) Tensorial Group Field Theory in Three Dimensions Authors: Sylvain Carrozza, Daniele Oriti, Vincent Rivasseau Categories: hep-th Comments: 47 pages, 8 figures, 2 tables Report-no: LPT-ORSAY 13-25, AEI-2013-167 \\ We address in this paper the issue of renormalizability for SU(2) Tensorial Group Field Theories (TGFT) with geometric Boulatov-type conditions in three dimensions. We prove that tensorial interactions up to degree 6 are just renormalizable without any anomaly. Our new models define the renormalizable TGFT version of the Boulatov model and provide therefore a new approach to quantum gravity in three dimensions. Among the many new technical results established in this paper are a general classification of just renormalizable models with gauge invariance condition, and in particular concerning properties of melonic graphs, the second order expansion of melonic two point subgraphs needed for wave-function renormalization. \\ ( http://arxiv.org/abs/1303.6772 , 497kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6828 Date: Wed, 27 Mar 2013 13:34:55 GMT (11kb) Title: Cosmological perturbations in $F(R)$ gravity Authors: Jiro Matsumoto Categories: hep-th astro-ph.CO gr-qc Comments: 15 pages \\ The quasi-static solutions of the matter density perturbation in $F(R)$ gravity models have been investigated in numerous papers. However, the oscillating solutions in $F(R)$ gravity models have not been enough investigated so far. In this paper, the oscillating solutions are also examined by using appropriate approximations. And the behaviors of the matter density perturbation in F(R) gravity models with singular evolutions of the physical parameters are shortly investigated as applications of the approximated calculations. \\ ( http://arxiv.org/abs/1303.6828 , 11kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6845 Date: Wed, 27 Mar 2013 14:45:10 GMT (128kb,D) Title: D6-Brane Model Building and Discrete Symmetries on T6/Z(2)xZ(6')xOR with Discrete Torsion Authors: Gabriele Honecker, Wieland Staessens Categories: hep-th hep-ph Comments: 15 pages; Proceedings of the Corfu Summer Institute 2012 Report-no: MITP/13-021 \\ We review several geometric aspects and properties of the orbifold T6/Z(2)xZ(6')xOR with discrete torsion, that are crucial with respect to global model building and the search for discrete gauge symmetries in the context of intersecting D6-brane models.

Charneski, M. Gomes, Leonardo Nascimento, Francisco Pe\~na Categories: hep-th \\ In this work the generation of generalized Chern-Simons terms in three dimensional quantum electrodynamics with high spatial derivatives is studied. We analyze the self-energy corrections to the gauge field propagator by considering an expansion of the amplitude up to third order in the external momenta. The divergences of the corrections are determined and explicit forms for the Chern-Simons terms with high derivatives are obtained. Some unusual aspects of the calculation are stressed and the existence of a smooth isotropic limit is proved. The transversality of the anisotropic gauge propagator is also discussed. \\ ( http://arxiv.org/abs/1303.6853 , 26kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6909 Date: Wed, 27 Mar 2013 17:44:32 GMT (114kb) Title: Leading singularities and off-shell conformal integrals Authors: James Drummond, Claude Duhr, Burkhard Eden, Paul Heslop, Jeffrey Pennington, Vladimir A. Smirnov Categories: hep-th hep-ph Comments: 60 pages, LaTeX, 2 figures Report-no: HU-Mathematik:2013-06, HU-EP-13/15, IPPP/13/09, DCPT/13/18, SLAC-PUB-15409, LAPTH-016/13, CERN-PH-TH/2013-058 \\ The three-loop four-point function of stress-tensor multiplets in N=4 super Yang-Mills theory contains two so far unknown, off-shell, conformal integrals, in addition to the known, ladder-type integrals. In this paper we evaluate the unknown integrals, thus obtaining the three-loop correlation function analytically. The integrals have the generic structure of rational functions multiplied by (multiple) polylogarithms. We use the idea of leading singularities to obtain the rational coefficients, the symbol - with an appropriate ansatz for its structure - as a means of characterising multiple polylogarithms, and the technique of asymptotic expansion of Feynman integrals to obtain the integrals in certain limits. The limiting behaviour uniquely fixes the symbols of the integrals, which we then lift to find the corresponding polylogarithmic functions. The final formulae are numerically confirmed. The techniques we develop can be applied more generally, and we illustrate this by analytically evaluating one of the integrals contributing to the same four-point function at four loops. This example shows a connection between the leading singularities and the entries of the symbol. \\ ( http://arxiv.org/abs/1303.6909 , 114kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6939 Date: Wed, 27 Mar 2013 19:41:41 GMT (232kb) Title: The 1/2 BPS Wilson loop in ABJM theory at two loops Authors: Marco S.

F. Hassan, Angnis Schmidt-May, Mikael von Strauss Categories: hep-th gr-qc Comments: Latex, 29 pages \\ In this paper we establish the correspondence between ghost-free bimetric theory and a class of higher derivative gravity actions, including conformal gravity and New Massive Gravity. We also characterize the relation between the respective equations of motion and classical solutions. We illustrate that, in this framework, the spin-2 ghost of higher derivative gravity is an artifact of the truncation to a 4-derivative theory. The analysis also gives a relation between the proposed partially massless (PM) bimetric theory and conformal gravity, showing, in particular, the equivalence of their equations of motion at the 4-derivative level. For the PM bimetric theory this provides further evidence for the existence of an extra gauge symmetry and the associated loss of a propagating mode away from de Sitter backgrounds. The new symmetry is an extension of Weyl symmetry which also suggests the PM bimetric theory as a ghost-free completion of conformal gravity. \\ ( http://arxiv.org/abs/1303.6940 , 31kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1303.6655 (*cross-listing*) Date: Tue, 26 Mar 2013 20:42:56 GMT (602kb) Title: Crossover physics in the non-equilibrium dynamics of quenched quantum impurity systems Authors: Romain Vasseur, Kien Trinh, Stephan Haas and Hubert Saleur Categories: cond-mat.str-el hep-th quant-ph Comments: 4.5 pages + supplementary material \\ A general framework is proposed to tackle analytically local quantum quenches in integrable impurity systems, combining a mapping onto a boundary problem with the form factor approach to boundary-condition-changing operators introduced in Phys. Rev. Lett. 80, 4370 (1998). We discuss how to compute exactly two central quantities of interest: the Loschmidt echo and the distribution of the work done during the quantum quench. Our results display an interesting crossover physics characterized by the energy scale T_b of the impurity corresponding to the Kondo temperature. We discuss in detail the non-interacting case as a paradigm and benchmark for more complicated integrable impurity models, and check our results using numerical methods. \\ ( http://arxiv.org/abs/1303.6655 , 602kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6716 (*cross-listing*) Date: Wed, 27 Mar 2013 01:04:11 GMT (568kb) Title: Symmetry protected entanglement renormalization Authors: Sukhwinder Singh, Guifre Vidal Categories: cond-mat.str-el hep-th \\ Entanglement renormalization is a real-space renormalization group (RG) transformation for quantum many-body systems. It generates the multi-scale entanglement renormalization ansatz (MERA), a tensor network capable of efficiently describing a large class of many-body ground states, including those of systems at a quantum critical point or with topological order. The MERA has also been proposed to be a discrete realization of the holographic principle of string theory. In this paper we propose the use of symmetric tensors as a mechanism to build a symmetry protected RG flow, and discuss two important applications of this construction. First, we argue that symmetry protected entanglement renormalization produces the proper structure of RG fixed-points, namely a fixed-point for each symmetry protected phase. Second, in the context of holography, we show that by using symmetric tensors, a global symmetry at the boundary becomes a local symmetry in the bulk, thus explicitly realizing in the MERA a characteristic feature of the AdS/CFT correspondence. \\ ( http://arxiv.org/abs/1303.6716 , 568kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6824 (*cross-listing*) Date: Wed, 27 Mar 2013 13:30:40 GMT (332kb) Title: Scalar Radiation in the Background of a Naked Singularity Authors: Anshuman Dey, Pratim Roy, Tapobrata Sarkar Categories: gr-qc hep-th Comments: 1 + 15 Pages, LaTeX, 6 .eps figures \\ We study scalar radiation spectra from a particle in circular orbit, in the background of the Janis-Newman-Winicour (JNW) naked singularity.

Wetterich Categories: astro-ph.CO gr-qc hep-th Comments: 5 pages \\ We discuss a cosmological model where the universe shrinks rather than expands during the radiation and matter dominated periods. Instead, the Planck mass and all particle masses grow exponentially. Together with a preceding inflationary phase and a late dark energy dominated epoch this model is compatible with all observations. It has no big bang singularity. There exist other, equivalent choices of coordinates or field variables for which the universe shows the usual expansion or is static during the radiation or matter dominated epochs. Predictions of this model for primordial density fluctuations created during inflation concern a spectral index n=0.97 and a tensor to scalar ratio r=0.13. \\ ( http://arxiv.org/abs/1303.6878 , 9kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6917 (*cross-listing*) Date: Wed, 27 Mar 2013 18:11:00 GMT (18kb) Title: Is there life beyond Quantum Mechanics? Authors: Anton Kapustin Categories: quant-ph hep-th math-ph math.MP Comments: 23 pages, latex \\ We formulate physically-motivated axioms for a physical theory which for systems with a finite number of degrees of freedom uniquely lead to Quantum Mechanics as the only nontrivial consistent theory. Complex numbers and the existence of the Planck constant common to all systems arise naturally in this approach. The axioms are divided into two groups covering kinematics and basic measurement theory respectively. We show that even if the second group of axioms is dropped, there are no deformations of Quantum Mechanics which preserve the kinematic axioms. Thus any theory going beyond Quantum Mechanics must represent a radical departure from the usual a priori assumptions about the laws of Nature. \\ ( http://arxiv.org/abs/1303.6917 , 18kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6929 (*cross-listing*) Date: Wed, 27 Mar 2013 19:08:22 GMT (2882kb) Title: Dynamical holographic QCD model for glueball and light meson spectra Authors: Danning Li and Mei Huang Categories: hep-ph hep-th Comments: 43 pages, 20 figures \\ In this work, we offer a systematic framework to describe the gluodynamics and chiral dynamics.We firstly construct a quenched dynamical holographic QCD (hQCD) model in the graviton-dilaton framework for the pure gluon system, then develop a dynamical hQCD model for the two flavor system in the graviton-dilaton-scalar framework by adding light flavors on the gluodynamical background. The dimension-2 dilaton background field $\Phi$ takes the same form as that in the soft-wall model and its square $\Phi^2$ can be identified as the dual field to the gauge invariant operator of the dimension-4 gluon condensate. The gluon condensate in the QCD vacuum breaks conformality and induces a deformed warp factor. Without introducing extra parameters but just self-consistently solving the deformed metric induced by the dilaton background field, we find that the scalar glueball spectra in the quenched dynamical model is in very well agreement with lattice data.For two flavor system in the graviton-dilaton-scalar framework, the deformed metric is self-consistently solved by considering both the chiral condensate and gluon condensate in the vacuum, which are responsible for the chiral symmetry breaking and linear confinement, respectively. It is found that the mixing between the chiral condensate and gluon condensate is important to produce the correct light flavor meson spectra. The pion form factor and the vector couplings are also investigated in the dynamical hQCD model. Besides, we give the criteria for the existence of linear quark potential from the metric structure, and show a negative quadratic dilaton background field is not favored in the graviton-dilaton framework. \\ ( http://arxiv.org/abs/1303.6929 , 2882kb) ------------------------------------------------------------------------------ \\ arXiv:1303.6931 (*cross-listing*) Date: Wed, 27 Mar 2013 19:17:33 GMT (13kb) Title: Degenerate states in the scalar boson spectrum. Is the Higgs Boson a Twin ? Authors: Berthold Stech Categories: hep-ph hep-th Comments: 6 pages \\ The extension of the standard model to $SU(3)_L\times SU(3)_R \times SU(3)_C$ is considered. Spontaneous symmetry breaking requires two $(3^*, 3, 1)$ Higgs field multiplets with a strong hierarchical structure of their vacuum expectation values. An invariant potential is constructed to provide for these vacuum expectation values. This potential gives masses to all scalar fields apart from the 15 Goldstone bosons. In case there exists a one-to-one correspondence between the vacuum expectation values of the two field multiplets, the scalar boson spectrum contains degenerate eigenstates. The lowest eigenstate has a mass near 123 GeV close to the Higgs-like particle discovered at the LHC. In one class of solutions this lowest state is a nearly degenerate twin state. Each member is a superposition of fields from both multiplets with about equal strength. The twins are non identical twins, namely different combinations of a conventional Higgs and a Higgs field which is not coupled to fermions, only to gauge bosons. A second class of solutions leads again to degenerate states but in this case the state near 123 GeV remains a single state even for identical low scale vacuum expectation values in both multiplets. \\ ( http://arxiv.org/abs/1303.6931 , 13kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1204.6380 replaced with revised version Wed, 27 Mar 2013 09:12:20 GMT (415kb) Title: Singularity-free model of electric charge in physical vacuum: Non-zero spatial extent and mass generation Authors: Vladimir Dzhunushaliev and Konstantin G.
