On the Eikonal Approximation in AdS Space
نویسندگان
چکیده
We explore the eikonal approximation to graviton exchange in AdS5 space, as relevant to scattering in gauge theories. We restrict ourselves to the regime where conformal invariance of the dual gauge theory holds, and to large ’t Hooft coupling where the computation involves pure gravity. We give a heuristic argument, a direct loop computation, and a shock wave derivation. The scalar propagator in AdS3 plays a key role, indicating that even at strong coupling, two-dimensional conformal invariance controls high-energy four-dimensional gaugetheory scattering.

High Energy Scattering in the AdS/CFT Correspondence
This work explores the celebrated AdS/CFT correspondence [1] in the regime of high energy scattering in Anti–de Sitter (AdS) spacetime. In particular, we develop the eikonal approximation to high energy scattering in AdS and explore its consequences for the dual Conformal Field Theory (CFT). Using position space Feynman rules, we rederive the eikonal approximation for high energy scattering in ...
متن کاملEikonal Approximation in AdS/CFT: Resumming the Gravitational Loop Expansion
We derive an eikonal approximation to high energy interactions in Anti–de Sitter spacetime, by generalizing a position space derivation of the eikonal amplitude in flat space. We are able to resum, in terms of a generalized phase shift, ladder and cross ladder graphs associated to the exchange of a spin j field, to all orders in the coupling constant. Using the AdS/CFT correspondence, the resul...
متن کاملOn The Pomeron at Large ’t Hooft Coupling
We begin the process of unitarizing the Pomeron at large ’t Hooft coupling. We do so first in the conformal regime, which applies to good accuracy to a number of real and toy problems in QCD. We rewrite the conformal Pomeron in the J-plane and transverse position space, and then work out the eikonal approximation to multiple Pomeron exchange. This is done in the context of a more general treatm...
متن کاملBFKL Pomeron at Weak Coupling
We consider correlators of N = 4 super Yang Mills of the form A ∼〈O1O2O 1O 2〉, where the operatorsO1 andO2 are scalar primaries. In particular, we analyze this correlator in the planar limit and in a Lorentzian regime corresponding to high energy interactions in AdS. The planar amplitude is dominated by a Regge pole whose nature varies as a function of the ’t Hooft coupling g. At large g, the p...
متن کاملElastic Parton-Parton Scattering from AdS/CFT
Using the AdS/CFT correspondence and the eikonal approximation, we evaluate the elastic parton-parton scattering amplitude at large N and strong coupling gN in N=4 SYM. We obtain a scattering amplitude with a Regge behavior that unitarizes at large √ s. For partons with masses m in the range √ s > m > √ −t, we suggest that our results may be of relevance to QCD in four dimensions. E-mail: rho@s...
