Buchbinder, Jaume Gomis and Filippo Passerini Categories: hep-th Comments: 42 pages, harvmac \\ We construct a new class of supersymmetric surface operators in N=4 SYM and find the corresponding dual supergravity solutions. We show that the insertion of the surface operator - which is given by a WZW model supported on the surface - appears by integrating out the localized degrees of freedom along the surface which arise microscopically from a D3/D7 brane intersection. Consistency requires constructing N=4 SYM in the D7 supergravity background and not in flat space. This enlarges the class of holographic gauge theories dual to string theory backgrounds to gauge theories in non-trivial supergravity backgrounds. The dual Type IIB supergravity solutions we find reveal - among other features - that the holographic dual gauge theory does indeed live in the D7-brane background. \\ ( http://arxiv.org/abs/0710.5170 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5172 Date: Fri, 26 Oct 2007 20:02:05 GMT (10kb) Title: Non-Gaussianities in New Ekpyrotic Cosmology Authors: Evgeny I. Buchbinder, Justin Khoury, Burt A. Ovrut Categories: hep-th Comments: 4 pages \\ New Ekpyrotic Cosmology is an alternative scenario of the early universe which relies on a phase of slow contraction before the big bang. We calculate the 3-point and 4-point correlation functions of primordial density perturbations and find a generically large non-Gaussian signal, just below the current sensitivity level of CMB experiments. This is in contrast with slow-roll inflation, which predicts negligible non-Gaussianity. The model is also distinguishable from alternative inflationary scenarios that yield large non-Gaussianity, such as DBI inflation and curvaton-like models, through the shape dependence of the correlation functions. Non-Gaussianity therefore provides a distinguishing and testable prediction of New Ekpyrotic Cosmology. \\ ( http://arxiv.org/abs/0710.5172 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5178 Date: Fri, 26 Oct 2007 20:54:55 GMT (16kb) Title: Hamilton-Jacobi Mechanics from Pseudo-Supersymmetry Authors: Paul K. Townsend Categories: hep-th Comments: 19 pages Report-no: DAMTP-2007-89 \\ For a general mechanical system, it is shown that each solution of the Hamilton-Jacobi equation defines an N=2 pseudo-supersymmetric extension of the system, such that the usual relation of the momenta to Hamilton's principal function is the `BPS' condition for preservation of 1/2 pseudo-supersymmetry. The examples of the relativistic and non-relativistic particle, in a general potential, are worked through in detail, and used to discuss the relation to cosmology and to supersymmetric quantum mechanics. \\ ( http://arxiv.org/abs/0710.5178 , 16kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5198 Date: Sat, 27 Oct 2007 00:07:13 GMT (68kb) Title: Strings Inside Walls in N=1 Super Yang-Mills Authors: S.Bolognesi Categories: hep-th Comments: 17 pages, 7 figures Report-no: FTPI-MINN-07/31 \\ We conjecture the existence of strings bounded inside walls in SU(N) $\N=1$ Super Yang-Mills theory. These strings carry $Z_{[k,N]}$ quantum number, where $[k,N]$ is the greatest common divisor between $k$, the charge of the wall, and $N$ the size of the gauge group. We provide field-theoretical arguments and string-theoretical evidences, both from MQCD and from gauge-gravity correspondence. We interpret this result from the point of view of the low-energy effective action living on the $k$-wall. It implies that this 2+1 field theory lives in a phase in which probe electric charges are confined modulo $[k,N]$ and screened when multiple of $[k,N]$. \\ ( http://arxiv.org/abs/0710.5198 , 68kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5203 Date: Sat, 27 Oct 2007 01:35:28 GMT (8kb) Title: S-matrix at spatial infinity Authors: Daniele Colosi (UNAM), Robert Oeckl (UNAM) Categories: hep-th Comments: 4 pages, LaTeX + revtex4 Report-no: UNAM-IM-MOR-2007-1 \\ We provide a new method to construct the S-matrix in quantum field theory. This method implements crossing symmetry manifestly by erasing the a priori distinction between in- and out-states. It allows the description of processes where the interaction weakens with distance in space, but remains strong in the center at all times. It should also be applicable to certain spacetimes where the conventional method fails due to lack of temporal asymptotic states. \\ ( http://arxiv.org/abs/0710.5203 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5232 Date: Sat, 27 Oct 2007 15:14:46 GMT (9kb) Title: From inflation to dark energy in the non-minimal modified gravity Authors: Shin'ichi Nojiri, Sergei D.

Odintsov at ICGA8 conference, Nara, Japan Report-no: YITP-07-73 \\ We consider the modified gravity non-minimally coupled with matter Lagrangian for the description of early-time and late-time universe. Such $F(R)$ ($F(G)$) gravity in the absence of non-minimal coupling is viable theory which passes the local tests and reproduces the $\Lambda$CDM era. For qualitatively similar choice of non-minimal gravitational coupling function it is shown that the unified description of early-time inflation and late-time cosmic acceleration is possible. It is interesting that matter (scalar) which supports the inflationary era is gravitationally screened at late times. Hence, it may be effectively invisible at current universe. \\ ( http://arxiv.org/abs/0710.5232 , 9kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5233 Date: Sat, 27 Oct 2007 15:17:32 GMT (14kb) Title: Intersecting non-SUSY branes and closed string tachyon condensation Authors: J. X. Lu, Shibaji Roy, Zhao-Long Wang and Rong-Jun Wu Categories: hep-th Comments: 17 pages Report-no: USTC-ICTS-07-23 \\ Following \cite{Bai:2006vv} we here consider the supergravity solutions representing the charged non-supersymmetric $p$-brane (for $1\leq p \leq 6$) intersecting with chargeless non-supersymmetric 1-brane and 0-brane of type II string theories. We show how these solutions nicely interpolate between black $p$-branes and the Kaluza-Klein ``bubble of nothing'' by continuously varying some parameters characterizing the solutions from one set of values to another. We propose that the interpolation can be interpreted as the closed string tachyon condensation, a stringy phenomenon, for $p \leq 4$. We argue that for $p=3$, the tachyon condensation can occur either outside or inside the horizon, but for other cases ($p \neq 3$) it occurs only inside the horizon. However, for $p>4$, we can not give such an interpretation since the black branes in those cases can not decay into static bubbles. We also show that the configurations indeed contain (chargeless) F-strings required for the closed string tachyons to appear causing the transitions to occur. \\ ( http://arxiv.org/abs/0710.5233 , 14kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5245 Date: Sat, 27 Oct 2007 16:52:50 GMT (315kb,D) Title: On the Matter of N=2 Matter Authors: C.

Using these, we develop a class of supersymmetric actions supplying a context for a systematic exploration of N = 2 matter theories, some of which include Hypermultiplet sectors in novel ways. We construct an N = 2 supersymmetric field theory in which the propagating fields are realized off-shell exclusively as Lorentz scalars and Weyl spinors and which involves a sector with precisely the R-charge assignments characteristic of Hypermultiplets. \\ ( http://arxiv.org/abs/0710.5245 , 315kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5267 Date: Sun, 28 Oct 2007 07:52:17 GMT (49kb) Title: Fermion excitations of a tense brane black hole Authors: H.

Cornell, Jason Doukas, Wade Naylor Categories: hep-th Comments: 7 pages, 1 figure \\ By finding the spinor eigenvalues for a single deficit angle (d-2)-sphere, we derive the radial potential for fermions on a d-dimensional black hole background that is embedded on a codimension two brane with conical singularity, where the deficit angle is related to the brane tension. From this we obtain the quasi-normal mode spectrum for bulk fermions on such a background. As a byproduct of our method, this also gives a rigorous proof for integer spin fields on the deficit 2-sphere. \\ ( http://arxiv.org/abs/0710.5267 , 49kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5269 Date: Sun, 28 Oct 2007 08:27:41 GMT (43kb) Title: Cyclic Universes from General Collisionless Braneworld Models Authors: E. N. Saridakis Categories: hep-th Comments: 16 pages, 1 figure, submitted for publication to Nucl. Phys. B \\ We investigate the full 5D dynamics of general braneworld models. Without making any further assumptions we show that cyclic behavior can arise naturally in a fraction of physically accepted solutions. The model does not require brane collisions, which in the stationary case remain fixed, and cyclicity takes place on the branes. We indicate that the cosmological constants play the central role for the realization of cyclic solutions and we show that its extremely small value on the observable universe makes the period of the cycles and the maximum scale factor astronomically large. \\ ( http://arxiv.org/abs/0710.5269 , 43kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5297 Date: Mon, 29 Oct 2007 18:08:43 GMT (130kb) Title: Deep inelastic scattering off a N=4 SYM plasma at strong coupling Authors: Y. Hatta, E. Iancu, and A.H. Mueller Categories: hep-th Comments: 36 pages, 3 figures \\ By using the AdS/CFT correspondence we study the deep inelastic scattering of an R-current off a N=4 supersymmetric Yang-Mills (SYM) plasma at finite temperature and strong coupling. Within the supergravity approximation valid when the number of colors is large, we compute the structure functions by solving Maxwell equations in the space-time geometry of the AdS_5 black three-brane. We find a rather sharp transition between a low energy regime where the scattering is weak and quasi-elastic, and a high-energy regime where the current is completely absorbed. The critical energy for this transition determines the plasma saturation momentum in terms of its temperature T and the Bjorken x variable: Q_s=T/x. These results suggest a partonic picture for the plasma where all the partons have transverse momenta below the saturation momentum and occupation numbers of order one. \\ ( http://arxiv.org/abs/0710.5297 , 130kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5339 Date: Mon, 29 Oct 2007 06:07:24 GMT (30kb) Title: Melting Crystal, Quantum Torus and Toda Hierarchy Authors: Toshio Nakatsu and Kanehisa Takasaki Categories: hep-th Comments: 30 pages, 4 figures \\ Searching for the integrable structures of supersymmetric gauge theories and topological strings, we study melting crystal, which is known as random plane partition, from the viewpoint of integrable systems. We show that a series of partition functions of melting crystals gives rise to a tau function of the one-dimensional Toda hierarchy, where the models are defined by adding suitable potentials, endowed with a series of coupling constants, to the standard statistical weight. These potentials can be converted to a commutative sub-algebra of quantum torus Lie algebra. This perspective reveals a remarkable connection between random plane partition and quantum torus Lie algebra, and substantially enables to prove the statement. Based on the result, we briefly argue the integrable structures of five-dimensional $\mathcal{N}=1$ supersymmetric gauge theories and $A$-model topological strings. The aforementioned potentials correspond to gauge theory observables analogous to the Wilson loops, and thereby the partition functions are translated in the gauge theory to generating functions of their correlators. In topological strings, we particularly comment on a possibility of topology change caused by condensation of these observables, giving a simple example. \\ ( http://arxiv.org/abs/0710.5339 , 30kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5342 Date: Mon, 29 Oct 2007 06:05:31 GMT (26kb) Title: Cosmological Density Fluctuations in Stochastic Gravity -- Formalism and Linear Analysis -- Authors: Yuko Urakawa, Kei-ichi Maeda Categories: hep-th Comments: 14 pages \\ We study primordial perturbations generated from quantum fluctuations of an inflaton based on the formalism of stochastic gravity. Integrating out the degree of freedom of the inflaton field, we analyze the time evolution of the correlation function of the curvature perturbation at tree level and compare it with the prediction made by the gauge-invariant linear perturbation theory. We find that our result coincides with that of the gauge-invariant perturbation theory if the e-folding from the horizon crossing time is smaller than some critical value ($\sim |$slow-roll parameter $|^{-1}$), which is the case for the scales of the observed cosmological structures. However, in the limit of the superhorizon scale, we find a discrepancy in the curvature perturbation, which suggests that we should include the longitudinal part of the gravitational field in the quantization of a scalar field even in stochastic gravity. \\ ( http://arxiv.org/abs/0710.5342 , 26kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5358 Date: Mon, 29 Oct 2007 09:18:33 GMT (35kb) Title: Level truncation analysis of exact solutions in open string field theory Authors: Tomohiko Takahashi Categories: hep-th Comments: 11 pages, 6 figures \\ We evaluate vacuum energy density of Schnabl's solution using the level truncation calculation and the total action including interaction terms.

Our results, which are applicable to excitations involving an arbitrary number of open strings, generalize the single string results of hep-th/0701067. The open strings we consider carry angular momentum on an S$^3$ embedded in the S$^5$ of the AdS$_5\times$S$^5$ background. The problem of computing the one loop anomalous dimensions is replaced with the problem of diagonalizing an interacting Cuntz oscillator Hamiltonian. Our Cuntz oscillator dynamics illustrates how the Chan-Paton factors for open strings propagating on multiple branes can arise dynamically. \\ ( http://arxiv.org/abs/0710.5372 , 120kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5378 Date: Mon, 29 Oct 2007 19:28:47 GMT (50kb) Title: Geometric Lagrangians for massive higher-spin fields Authors: D.

B. Paranjape Categories: hep-th Comments: 19 pages, 2 figures, colour viewing helpful Report-no: UdeM-GPP-TH-07-163 \\ Conformal gravity is a generally covariant theory of gravitational interactions, which benefits from an additional infinite dimensional invariance, invariance under local conformal transformations. However, for conformal gravity to be phenomenologically viable requires that the conformal symmetry is not manifest at the energy scales of the other known physical forces. Hence we require a mechanism for the spontaneous breaking of conformal invariance. In this paper we study the possibility that conformal invariance is spontaneously broken due to interactions with conformally coupled matter fields. The vacuum of the theory admits conformally non-invariant solutions corresponding to maximally symmetric space-times and variants thereof. These are either de Sitter space-time or anti-de Sitter space-time in the full four space-time dimensions or in a lower dimensional sub-space. We consider in particular a linearized gravitational perturbation around the anti-de Sitter background. Exploiting the conformal flatness of this space-time, the derivation of gravitational radiation can be done in Minkowskian space-time. We show, to second order, that free gravitational waves carry zero energy-momentum. We also show the possibility of domain wall solitons interpolating between ground states of spontaneously broken conformal symmetry. These solitons necessarily require the vanishing of the scalar field, repudiating the recent suggestion \cite{flanagan} that the conformal symmetry could be quarantined to a sterile sector of the theory by choosing an appropriate field redefinition. \\ ( http://arxiv.org/abs/0710.5402 , 24kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5438 Date: Mon, 29 Oct 2007 14:08:51 GMT (7kb) Title: Kinematical Reduction of Spatial Degrees of Freedom and Holographic Relation in Yang's Quantized Space-Time Algebra Authors: Sho Tanaka Categories: hep-th Comments: 9pages \\ We try to find the origin of the holographic principle in the Lorentz-covariant Yang's quantized space-time algebra (YSTA). YSTA, which is intrinsically equipped with short- and long-scale parameters, $\lambda$ and $R$, gives a finite number of spatial degrees of freedom for any bounded spatial region, providing a basis for divergence-free quantum field theory. Furthermore, it gives a definite kinematical reduction of spatial degrees of freedom, compared with the ordinary lattice space. On account of the latter fact, we find a certain kind of kinematical holographic relation in YSTA, which can be regarded as the primordial form of the holographic principle suggested so far in the framework of the present quantum theory that appears now in the contraction limit of YSTA, $\lambda \to 0$ and $R \to \infty.$ \\ ( http://arxiv.org/abs/0710.5438 , 7kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5469 Date: Mon, 29 Oct 2007 16:13:54 GMT (10kb) Title: On the effective action of D-brane-anti-D-brane system Authors: Mohammad R.

We consider two prescriptions for the trace in the non-abelian tachyon DBI action. The usual trace and the symmetric trace prescription. The former gives an action for the D\bar{D} system which reduces to the action proposed by A.Sen for coincident branes. The latter gives a different action which is consistent with the S-matrix element calculations. \\ ( http://arxiv.org/abs/0710.5469 , 10kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5480 Date: Mon, 29 Oct 2007 16:52:27 GMT (216kb) Title: Eikonal Methods in AdS/CFT: Regge Theory and Multi-Reggeon Exchange Authors: Lorenzo Cornalba Categories: hep-th Comments: 25 pages, 6 figures \\ We analyze conformal field theory 4-point functions of the form A ~ O_1(x_1) O_2(x_2) O_1(x_3) O_2(x_4), where the operators O_i are scalar primaries. We show that, in the Lorentzian regime, the limit x_1 -> x_3 is dominated by the exchange of conformal partial waves of highest spin. When partial waves of arbitrary spin contribute to A, the behavior of the Lorentzian amplitude for x_1 -> x_3 must be analyzed using complex-spin techniques, leading to a generalized Regge theory for CFT's. Whenever the CFT is dual to a string theory, the string tree-level contribution A_tree to the amplitude A presents a Regge pole corresponding the a gravi-reggeon exchange. In this case, we apply the impact parameter representation for CFT amplitudes, previously developed, to analyze multiple reggeon exchanges in the eikonal limit. As an example, we apply these general techniques to N=4 super-Yang-Mills theory in d=4 in the limit of large 't Hooft coupling, including the leading string corrections to pure graviton exchange. \\ ( http://arxiv.org/abs/0710.5480 , 216kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5483 Date: Mon, 29 Oct 2007 18:42:24 GMT (42kb) Title: Holographic Entanglement Entropy and Phase Transitions at Finite Temperature Authors: Alberto Faraggi, Leopoldo A.

The crucial ingredient for this is the infinite tower of vector mesons in the approximations made which share features that are characteristic of the quenched approximation in lattice QCD. We approximate the infinite sum by contributions from the lowest four vector mesons of the tower which turn out to saturate the charge and magnetic moment sum rules within a few percent and compute them totally free of unknown parameters for momentum transfers Q^2 less than 1GeV^2. We identify certain observables that can be reliably computed within the approximations and others that are not, and discuss how the improvement of the latter can enable one to bring holographic QCD closer to QCD proper. \\ ( http://arxiv.org/abs/0710.4615 , 90kb) ------------------------------------------------------------------------------ \\ arXiv:0710.4992 (*cross-listing*) Date: Fri, 26 Oct 2007 05:44:24 GMT (23kb) Title: Non-minimal isotropic cosmological model with Yang-Mills and Higgs fields Authors: A. B. Balakin, H. Dehnen, A. E. Zayats Categories: gr-qc astro-ph hep-th Comments: 14 pages, submitted to IJMPD \\ We establish a non-minimal Einstein-Yang-Mills-Higgs model, which contains six coupling parameters. First three parameters relate to the non-minimal coupling of non-Abelian gauge field and gravity field, two parameters describe the so-called derivative non-minimal coupling of scalar multiplet with gravity field, and sixth parameter is a standard parameter of coupling of scalar field with curvature scalar. The formulated six-parameter non-minimal Einstein-Yang-Mills-Higgs model is applied to Cosmology. We show that there exists a unique exact cosmological solution of the de Sitter type for a special choice of the coupling parameters. The non-minimally extended Yang-Mills and Higgs equations are satisfied for arbitrary gauge and scalar field, when the coupling parameters are specifically related to the constant curvature of the isotropic space-time. Basing on this special exact solution, we discuss the problem of a hidden anisotropy of the Yang-Mills field, and give an explicit example that the non-minimal coupling can effectively screen the anisotropy induced by the Yang-Mills field and thus restore the isotropy of the model. \\ ( http://arxiv.org/abs/0710.4992 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:0710.5001 (*cross-listing*) Date: Fri, 26 Oct 2007 12:40:27 GMT (11kb) Title: Anisotropic inharmonic Higgs oscillator and related (MICZ-)Kepler-like systems Authors: Armen Nersessian and Vahagn Yeghikyan Categories: math-ph hep-th math.MP quant-ph Comments: 7 pages \\ We propose the integrable (pseudo)spherical generalization of the four-dimensional anisotropic oscillator with additional nonlinear potential.
