Nonasymptotic critical behavior from field theory

C. Bagnuls, C. Bervillier

The obtention (up to five or six loop orders) of nonasymptotic critical behavior, above and below Tc, from the field theoretical framework is presented and discussed.

String Fluctuations, AdS/CFT and the Soft Pomeron Intercept

Romuald A. Janik

We study high energy scattering amplitudes in a strongly coupled (confining) gauge theory using the AdS/CFT correspondence. The scattering described by a Wilson line/loop correlati…

Generalized Lorentzian Triangulations and the Calogero Hamiltonian

P. Di Francesco, E. Guitter, C. Kristjansen

We introduce and solve a generalized model of 1+1D Lorentzian triangulations in which a certain subclass of outgrowths is allowed, the occurrence of these being governed by a coupl…

Supersymmetric higher-derivative actions in ten and eleven dimensions, the associated superalgebras and their formulation in superspace

Kasper Peeters, Pierre Vanhove, Anders Westerberg

Higher-derivative terms in the string and M-theory effective actions are strongly constrained by supersymmetry. Using a mixture of techniques, involving both string amplitude calcu…

Dilaton Stabilization in Effective Type I String Models

S. A. Abel, G. Servant

We show that the dilaton and T-moduli can be stabilized by a single gaugino condensation mechanism in the four-dimensional effective field theory derived from Type IIB orientifolds…

Skyrmions in the Quantum Hall effect and noncommutative solitons

V. Pasquier

It has been recently shown that solitons are fundamental classical solutions of non-commutative field theories. We reconsider this issue from the standpoint of the Hall effect and…

One-point functions in perturbed boundary conformal field theories

P. Dorey, M. Pillin, R. Tateo +1

We consider the one-point functions of bulk and boundary fields in the scaling Lee-Yang model for various combinations of bulk and boundary perturbations. The one-point functions o…

Supergravity Description of Non-BPS Branes

Philippe Brax, Gautam Mandal, Yaron Oz

We construct supergravity solutions that correspond to N Dp-branes coinciding with \bar{N} \bar{Dp}-branes. We study the physical properties of the solutions and analyse the superg…

Exact Solution of the Three-color Problem on a Random Lattice

Ivan K. Kostov

We present the exact solution of the Baxter's three-color problem on a random planar graph, using the random-matrix formulation of the problem, given by B. Eynard and C. Kristjanse…

Note on irreducible approach to reducible second-class constraints

C. Bizdadea, A. Constantin, S. O. Saliu

An irreducible canonical approach to reducible second-class constraints is given. The procedure is illustrated on gauge-fixed two-forms.

Towards the matrix model of M-theory on a lattice

R. A. Janik, J. Wosiek

The Wilson discretization of the dimensionally reduced supersymmetric Yang-Mills theory is constructed. This gives a lattice version of the matrix model of M-theory. An SU(2) model…

Minimal surfaces and Reggeization in the AdS/CFT correspondence

R. A. Janik, R. Peschanski

We address the problem of computing scattering amplitudes related to the correlation function of two Wilson lines and/or loops elongated along light-cone directions in strongly cou…

A Comment on Self-Tuning and Vanishing Cosmological Constant in the Brane World

Stefan Forste, Zygmunt Lalak, Stephane Lavignac +1

In this note we elaborate on various five dimensional contributions to the effective 4D cosmological constant in brane systems. In solutions with vanishing 5D cosmological constant…

Exact Renormalization Group Equations. An Introductory Review

C. Bagnuls, C. Bervillier

We critically review the use of the exact renormalization group equations (ERGE) in the framework of the scalar theory. We lay emphasis on the existence of different versions of th…
