A. Bytsenko and A. Tureanu Categories: hep-th gr-qc Comments: 20 pages \\ Algebraic aspects of the computation of partition functions for quantum gravity and black holes in $AdS_3$ are discussed. We compute the sub-leading quantum corrections to the Bekenstein-Hawking entropy. It is shown that the quantum corrections to the classical result can be included systematically by making use of the comparison with conformal field theory partition functions, via the $AdS_3/CFT_2$ correspondence. This leads to a better understanding of the role of modular and spectral functions, from the point of view of the representation theory of infinite-dimensional Lie algebras. Besides, the sum of known quantum contributions to the partition function can be presented in a closed form, involving the Patterson-Selberg spectral function. These contributions can be reproduced in a holomorphically factorized theory whose partition functions are associated with the formal characters of the Virasoro modules. We propose a spectral function formulation for quantum corrections to the elliptic genus from supergravity states. \\ ( http://arxiv.org/abs/1304.7021 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7085 Date: Fri, 26 Apr 2013 07:58:51 GMT (7kb) Title: Entropy for curvature squared gravity using surface term and auxiliary field Authors: Kyosuke Hirochi Categories: hep-th gr-qc Comments: 7 pages \\ We compute the entropies for general curvature squared gravities in arbitrary dimensions using the conserved charge and Virasoro algebra from surface term. We introduce an auxiliary tensor field in order to obtain the boundary action which establish a variational principle. Our results reproduce those in some specific models, that is, the Gauss-Bonnet, new massive gravity (NMG), and critical gravity. \\ ( http://arxiv.org/abs/1304.7085 , 7kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7097 Date: Fri, 26 Apr 2013 08:50:54 GMT (78kb) Title: A New Model of Holographic QCD and Chiral Condensate in Dense Matter Authors: Shigenori Seki, Sang-Jin Sin Categories: hep-th hep-ph nucl-th Comments: 23 pages, 6 figures \\ We consider the model of holographic QCD with asymptotic freedom and gluon condensation in its vacuum. It consists of the color D4-branes and D0-branes as a background and the flavor D8-branes as a probe. By taking a specific field theory limit, the effective coupling decreases to vanish in UV region. We then introduce the uniformly distributed baryons in terms of the baryon vertices and study the density dependence of chiral condensate, which is evaluated using the worldsheet instanton method. In the confined phase, the chiral condensate as a function of density monotonically decreases in high baryon density. Such behavior is in agreement with the expectation, while in extremely low density it increases. We attribute this anomaly to the incorrect approximation of uniformity in very low density. In the deconfined phase the chiral condensate monotonically decreases in the whole region of density. \\ ( http://arxiv.org/abs/1304.7097 , 78kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7100 Date: Fri, 26 Apr 2013 09:06:54 GMT (21kb) Title: Dynamics of Entanglement Entropy from Einstein Equation Authors: Masahiro Nozaki, Tokiro Numasawa, Andrea Prudenziati, Tadashi Takayanagi Categories: hep-th Comments: 25 pages Report-no: YITP-13-29, IPMU-13-0083 \\ We study the dynamics of entanglement entropy for weakly excited states in conformal field theories by using the AdS/CFT. This is aimed at a first step to find a counterpart of Einstein equation in the CFT language. In particular, we point out that the entanglement entropy satisfies differential equations which directly correspond to the Einstein equation in several setups of AdS/CFT. We also define a quantity called entanglement density in higher dimensional field theories and study its dynamical property for weakly excited states in conformal field theories. \\ ( http://arxiv.org/abs/1304.7100 , 21kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7104 Date: Fri, 26 Apr 2013 09:44:35 GMT (383kb,D) Title: Dynamical Black Holes in 2+1 Dimensions Authors: Mario Flory and Ivo Sachs Categories: hep-th gr-qc Comments: 27 pages, 5 figures Report-no: LMU-ASC 21/13, MPP-2013-109 \\ We investigate the global structure of a recently discovered simple exact, non-stationary solution of topologically massive and new massive gravity with the asymptotic charges of an undeformed BTZ black hole. We establish the existence of a timelike singularity in the causal structure of the spacetime even in the absence of angular momentum. The dynamical trapping and event horizons are determined and we investigate the evolution of the outer horizon showing that it may increase or decrease with time, depending on the value of the mass parameter. Finally, we test two proposals for dynamical entropy on this solution, one of them depending on the Kodama vector. In addition we show that the Kodama vector leads to the correct entropy for all stationary black holes in 2+1 dimensions. \\ ( http://arxiv.org/abs/1304.7104 , 383kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7135 Date: Fri, 26 Apr 2013 12:03:29 GMT (44kb,D) Title: One-loop quantum gravity from a worldline viewpoint Authors: Fiorenzo Bastianelli and Roberto Bonezzi Categories: hep-th gr-qc Comments: 23 pages \\ We develop a worldline approach to quantum gravity in D=4. Using the background field method we consider the covariantly gauge fixed Einstein-Hilbert action with cosmological constant, and find a worldline representation of the differential operators identified by its quadratic approximation. We test it by computing the correct one-loop divergencies. Alternative worldline methods, such as the use of the O(4) spinning particle that is known to describe correctly the propagation of a massless spin 2 particle in D=4, find obstructions in the coupling to an arbitrary background metric, apparently preventing a more extensive use in perturbative descriptions of quantum gravity. We expect that our model might simplify calculations of one-loop amplitudes with respect to standard quantum field theoretical methods. \\ ( http://arxiv.org/abs/1304.7135 , 44kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7159 Date: Fri, 26 Apr 2013 13:30:00 GMT (27kb,D) Title: Corfu lectures on wall-crossing, multi-centered black holes, and quiver invariants Authors: Boris Pioline Categories: hep-th math.AG Comments: 19 pages, 1 figure; prepared for the Proceedings of the Corfu Summer Institute 2012 "School and Workshops on Elementary Particle Physics and Gravity", September 8-27, 2012 Report-no: CERN-PH-TH/2013-087 \\ The BPS state spectrum in four-dimensional gauge theories or string vacua with N=2 supersymmetries is well known to depend on the values of the parameters or moduli at spatial infinity. The BPS index is locally constant, but discontinuous across real codimension-one walls where some of the BPS states decay. By postulating that BPS states are bound states of more elementary constituents carrying their own degrees of freedom and interacting via supersymmetric quantum mechanics, we provide a physically transparent derivation of the universal wall-crossing formula which governs the jump of the index. The same physical picture suggests that at any point in moduli space, the total index can be written as a sum of contributions from all possible bound states of elementary, absolutely stable constituents with the same total charge. For D-brane bound states described by quivers, this `Coulomb branch formula' predicts that the cohomology of quiver moduli spaces is uniquely determined by certain `pure-Higgs' invariants, which are the microscopic analogues of single-centered black holes. These lectures are based on joint work with J. Manschot and A. Sen. \\ ( http://arxiv.org/abs/1304.7159 , 27kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7177 Date: Sun, 14 Apr 2013 05:47:38 GMT (36kb) Title: Continuous Wavelet Transform in Quantum Field Theory Authors: Mikhail V. Altaisky and Natalia E. Kaputkina Categories: hep-th Comments: 14 pages, RevTex, 8 eps figures \\ We describe the application of the continuous wavelet transform to calculation of the Green functions in quantum field theory: scalar $\phi^4$ theory, quantum electrodynamics, quantum chromodynamics. The method of continuous wavelet transform in quantum field theory presented in M.Altaisky Phys. Rev. D81(2010)125003 for the scalar $\phi^4$ theory, consists in substitution of the local fields $\phi(x)$ by those dependent on both the position $x$ and the resolution $a$. The substitution of the action $S[\phi(x)]$ by the action $S[\phi_a(x)]$ makes the local theory into nonlocal one, and implies the causality conditions related to the scale $a$, the region causality C. Christensen and L. Crane, J.Math. Phys 46 (2005) 122502. These conditions make the Green functions $G(x_1,a_1,..., x_n,a_n)=<\phi_{a_1}(x_1)...\phi_{a_n}(x_n)> $ finite for any given set of regions by means of an effective cutoff scale $A=\min (a_1,...,a_n)$. \\ ( http://arxiv.org/abs/1304.7177 , 36kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7229 Date: Fri, 26 Apr 2013 16:56:03 GMT (33kb,D) Title: Properties of Causal Holographic Information Authors: Ben Freivogel and Benjamin Mosk Categories: hep-th \\ Causal holographic information [1] is a variant of the Ryu-Takayanagi proposal for the entanglement entropy of a spatial region in the context of AdS/CFT, but with the bulk surface defined by causality rather than extremality. We investigate the properties of causal holographic information, focusing in particular on the universal coefficient of the logarithmically divergent term. We find that this coefficient contains a novel conformal invariant that cannot be written as an integral of local quantities. By considering higher curvature corrections in the bulk, we identify the coefficient of the a and c central charges in 4 dimensions. Finally, we speculate about which CFT quantity could correspond to the causal holographic information. \\ ( http://arxiv.org/abs/1304.7229 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7247 Date: Fri, 26 Apr 2013 18:09:38 GMT (461kb) Title: Probing the quantum nature of spacetime by diffusion Authors: Gianluca Calcagni, Astrid Eichhorn and Frank Saueressig Categories: hep-th cond-mat.stat-mech gr-qc Comments: 14 pages, 5 figures \\ Many approaches to quantum gravity have resorted to diffusion processes to characterize the spectral properties of the resulting quantum spacetimes. We critically discuss these quantum-improved diffusion equations and point out that a crucial property, namely positivity of their solutions, is not preserved automatically. We then construct a novel set of diffusion equations with positive semi-definite probability densities, applicable to Asymptotically Safe gravity, Horava-Lifshitz gravity and Loop Quantum Gravity. These recover all previous results on the spectral dimension and shed further light on the structure of the quantum spacetimes by assessing the underlying stochastic processes. Pointing out that manifestly different diffusion processes lead to the same spectral dimension, we propose the probability distribution of the diffusion process as a refined probe of quantum spacetime. \\ ( http://arxiv.org/abs/1304.7247 , 461kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7252 Date: Fri, 26 Apr 2013 18:37:43 GMT (17kb) Title: On DIS Wilson coefficients in N = 4 super Yang-Mills theory Authors: Lorenzo Bianchi, Valentina Forini, Anatoly V. Kotikov Categories: hep-th hep-ph Comments: 11 pages Report-no: HU-EP-13/19 \\ In this note we evaluate Wilson coefficients for "deep inelastic scattering" (DIS) in N=4 SYM theory at NLO in perturbation theory, using as a probe an R-symmetry conserved current. They exhibit uniform transcendentality and coincide with the piece of highest transcendentality in the corresponding QCD Wilson coefficients. We extract from the QCD result a NNLO prediction for the N=4 SYM Wilson coefficient, and comment on the features of its Regge limit asymptotics. \\ ( http://arxiv.org/abs/1304.7252 , 17kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7263 Date: Fri, 26 Apr 2013 19:42:59 GMT (581kb,D) Title: Classical Space-Times from the S Matrix Authors: Duff Neill (MIT) and Ira Z. Rothstein (CMU) Categories: hep-th gr-qc hep-ph \\ We show that classical space-times can be derived directly from the S-matrix for a theory of massive particles coupled to a massless spin two particle. As an explicit example we derive the Schwarzchild space-time as a series in $G_N$. At no point of the derivation is any use made of the Einstein-Hilbert action or the Einstein equations. The intermediate steps involve only on-shell S-matrix elements which are generated via BCFW recursion relations and unitarity sewing techniques. The notion of a space-time metric is only introduced at the end of the calculation where it is extracted by matching the potential determined by the S-matrix to the geodesic motion of a test particle. Other static space-times such as Kerr follow in a similar manner. Furthermore, given that the procedure is action independent and depends only upon the choice of the representation of the little group, solutions to Yang-Mills (YM) theory can be generated in the same fashion. Moreover, the squaring relation between the YM and gravity three point functions shows that the seeds that generate solutions in the two theories are algebraically related. From a technical standpoint our methodology can also be utilized to calculate quantities relevant for the binary inspiral problem more efficiently than the more traditional Feynman diagram approach. \\ ( http://arxiv.org/abs/1304.7263 , 581kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7267 Date: Fri, 26 Apr 2013 19:58:27 GMT (69kb) Title: Polylogarithms, Multiple Zeta Values and Superstring Amplitudes Authors: Johannes Broedel, Oliver Schlotterer, Stephan Stieberger Categories: hep-th hep-ph math.NT Comments: 79 pages, LaTeX Report-no: DAMTP-2013-22, AEI-2013-194, MPP-2013-119 \\ A formalism is provided to calculate tree amplitudes in open superstring theory for any multiplicity at any order in the inverse string tension. We point out that the underlying world-sheet disk integrals share substantial properties with color-ordered tree amplitudes in Yang-Mills field theories. In particular, we closely relate world-sheet integrands of open-string tree amplitudes to the Kawai-Lewellen-Tye representation of supergravity amplitudes. This correspondence helps to reduce the singular parts of world-sheet disk integrals -including their string corrections- to lower-point results. The remaining regular parts are systematically addressed by polylogarithm manipulations. \\ ( http://arxiv.org/abs/1304.7267 , 69kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1304.7020 (*cross-listing*) Date: Thu, 25 Apr 2013 20:19:47 GMT (59kb) Title: Charged black holes on Kaluza-Klein bubbles Authors: Jutta Kunz, Petya G.

More specifically we discuss the configurations describing two black holes sitting on a Kaluza-Klein bubble and also the general charged static black Saturn balanced by a Kaluza-Klein bubble. A straightforward extension of the solution generating technique leads to a new solution describing the charged static black Saturn on the Taub-bolt instanton.

Smillie, Chris D. White Categories: hep-ph hep-th Comments: 57 pages, 21 figures Report-no: Edinburgh 2013/07 \\ We study the structure of soft gluon corrections to multi-leg scattering amplitudes in a non-Abelian gauge theory by analysing the corresponding product of semi-infinite Wilson lines. We prove that diagrams exponentiate such that the colour factors in the exponent are fully connected. This completes the generalisation of the non-Abelian exponentiation theorem, previously proven in the case of a Wilson loop, to the case of multiple Wilson lines in arbitrary representations of the colour group. Our proof is based on the replica trick in conjunction with a new formalism where multiple emissions from a Wilson line are described by effective vertices, each having a connected colour factor. The exponent consists of connected graphs made out of these vertices. We show that this readily provides a general colour basis for webs. We further discuss the kinematic combinations that accompany each connected colour factor, and explicitly catalogue all three-loop examples, as necessary for a direct computation of the soft anomalous dimension at this order. \\ ( http://arxiv.org/abs/1304.7040 , 2016kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7042 (*cross-listing*) Date: Thu, 25 Apr 2013 23:10:54 GMT (634kb) Title: Non-Gaussianities and Curvature Perturbations from Hybrid Inflation Authors: S\'ebastien Clesse, Bj\"orn Garbrecht, Yi Zhu Categories: astro-ph.CO gr-qc hep-ph hep-th Comments: 17 pages, 5 figures Report-no: TUM-HEP-885/13 \\ For the original hybrid inflation as well as the supersymmetric F-term and D-term hybrid models, we calculate the level of non-gaussianities and the power spectrum of curvature perturbations generated during the waterfall, taking into account the contribution of entropic modes. We focus on the regime of mild waterfall, in which inflation continues for more than about 60 e-folds N during the waterfall. We find that the associated f_nl parameter goes typically from f_nl \simeq -1 / N_exit in the regime with N >> 60, where N_exit is the number of e-folds between the time of Hubble exit of a pivot scale and the end of inflation, down to f_nl ~-0.3 when N \gtrsim 60, i.e. much smaller in magnitude than the current bound from Planck. Considering only the adiabatic perturbations, the power spectrum is red, with a spectral index n_s = 1 - 4 / N_exit, in the case N >> 60, whereas in the case N \gtrsim 60, it increases up to unity. Including the contribution of entropic modes does not change the observable predictions in the first case. However, in the second case, they are a relevant source for the power spectrum of curvature perturbations, of which the amplitude increases by several orders of magnitudes and can lead to black hole formation. We conclude that due to the important contribution of entropic modes, the parameter space leading to a mild waterfall phase is excluded by CMB observations for all the considered models. \\ ( http://arxiv.org/abs/1304.7042 , 634kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7071 (*cross-listing*) Date: Fri, 26 Apr 2013 06:05:06 GMT (57kb) Title: Harmonic Sums, Polylogarithms, Special Numbers, and their Generalizations Authors: Jakob Ablinger and Johannes Bl\"umlein Categories: math-ph cs.SC hep-ph hep-th math.AG math.MP Comments: 30 pages Latex, 3 Figures, 1 style file, Cintribution to: "Integration, Summation and Special Functions in Quantum Field Theory", to appear at Springer Verlag, Vienna Report-no: DESY 13-073, DO-TH 13/10, SFB/CPP-13-26, LPN13-025 \\ In these introductory lectures we discuss classes of presently known nested sums, associated iterated integrals, and special constants which hierarchically appear in the evaluation of massless and massive Feynman diagrams at higher loops. These quantities are elements of stuffle and shuffle algebras implying algebraic relations being widely independent of the special quantities considered. They are supplemented by structural relations. The generalizations are given in terms of generalized harmonic sums, (generalized) cyclotomic sums, and sums containing in addition binomial and inverse-binomial weights. To all these quantities iterated integrals and special numbers are associated. We also discuss the analytic continuation of nested sums of different kind to complex values of the external summation bound N. \\ ( http://arxiv.org/abs/1304.7071 , 57kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7208 (*cross-listing*) Date: Fri, 26 Apr 2013 15:50:29 GMT (12kb) Title: Asymptotic formulas for coefficients of inverse theta functions Authors: Kathrin Bringmann, Jan Manschot Categories: math.NT hep-th Comments: 11 pages \\ We determine asymptotic formulas for the coefficients of a natural class of negative index and negative weight Jacobi forms.

This mechanism, also known as k-mouflage, allows to hide via non linear effects - typically for source distances smaller than a so-called Vainshtein radius which depends on the source and on the theory considered - some degrees of freedom whose effects are then only left important at large distances, e.g. for cosmology. It is introduced here in non linear Fierz-Pauli theories (massive gravities), including the dRGT theories, in their decoupling limits, as well as in other models such as DGP model or generalized Galileons. This presentation is self-contained and before discussing the Vainshtein mechanism we introduce some useful results and concepts concerning massive gravity, such as the vDVZ discontinuity, the decoupling limits or the Boulware-Deser ghost. \\ ( http://arxiv.org/abs/1304.7240 , 37kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7249 (*cross-listing*) Date: Fri, 26 Apr 2013 18:20:36 GMT (423kb,D) Title: Perturbative Non-Equilibrium Thermal Field Theory to all Orders in Gradient Expansion Authors: Peter Millington and Apostolos Pilaftsis Categories: hep-ph astro-ph.CO hep-th Comments: 7 pages, 4 figures Report-no: MAN/HEP/2013/06 \\ We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices. The resulting time-dependent diagrammatic perturbation series are free of pinch singularities without the need for quasi-particle approximation or effective resummation of finite widths. After arriving at a physically meaningful definition of particle number densities, we derive master time evolution equations for statistical distribution functions, which are valid to all orders in perturbation theory and to all orders in a gradient expansion. For a scalar model, we perform a loopwise truncation of these evolution equations, whilst still capturing fast transient behaviour, which is found to be dominated by energy-violating processes, leading to the non-Markovian evolution of memory effects. \\ ( http://arxiv.org/abs/1304.7249 , 423kb) ------------------------------------------------------------------------------ \\ arXiv:1304.7265 (*cross-listing*) Date: Fri, 26 Apr 2013 19:50:43 GMT (46kb) Title: Graviton Corrections to Vacuum Polarization during Inflation Authors: Katie E.
