Eikonal Approximation in AdS/CFT: Conformal Partial Waves and Finite N Four-Point Functions
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We introduce the impact-parameter representation for conformal field theory correlators of the form A ~ < O_1 O_2 O_1 O_2 >. This representation is appropriate in the eikonal kinem…
Eikonal Approximation in AdS/CFT: From Shock Waves to Four-Point Functions
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We initiate a program to generalize the standard eikonal approximation to compute amplitudes in Anti-de Sitter spacetimes. Inspired by the shock wave derivation of the eikonal ampl…
Radion Stabilization In 5D SUGRA
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We present a detailed study of radion stabilization within 5D conformal SUGRA compactified on an orbifold. We use an effective 4D superfield description developed in…
From Fundamental Strings to Small Black Holes
Lorenzo Cornalba, Miguel S. Costa, Joao Penedones +1
We give evidence in favour of a string/black hole transition in the case of BPS fundamental string states of the Heterotic string. Our analysis goes beyond the counting of degrees…
Strings as Multi-Particle States of Quantum Sigma-Models
Nikolay Gromov, Vladimir Kazakov, Kazuhiro Sakai +1
We study the quantum Bethe ansatz equations in the O(2n) sigma-model for hysical particles on a circle, with the interaction given by the Zamolodchikovs' S-matrix, in view of its a…
4D Superfield Reduction of 5D Orbifold SUGRA and Heterotic M-theory
Filipe Paccetti Correia, Michael G. Schmidt, Zurab Tavartkiladze
We present a detailed study of the reduction to 4D of 5D supergravity compactified on the S^1/Z_2 orbifold. For this purpose we develop and employ a recently proposed N=1 conformal…
