Diffractive Vector Meson Photoproduction from Dual String Theory
Peter G. O. Freund, Horatiu Nastase
We study diffractive vector meson photoproduction using string theory via AdS/CFT. The large behavior of the cross sections for the scattering of the vector meson on a prot…
Subleading-color contributions to gluon-gluon scattering in N=4 SYM theory and relations to N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We study the subleading-color (nonplanar) contributions to the four-gluon scattering amplitudes in N=4 supersymmetric SU(N) Yang-Mills theory. Using the formalisms of Catani and of…
AdS-CFT and the RHIC fireball
Horatiu Nastase
In this talk I will review my work on the description of high energy scattering in QCD, in particular the fireball observed at RHIC, as well as predictions for the LHC. The aim is…
Two-loop graviton scattering relation and IR behavior in N=8 supergravity
Stephen G. Naculich, Horatiu Nastase, Howard J. Schnitzer
We derive an ABDK-like relation between the one- and two-loop four-graviton amplitudes in N=8 supergravity. Specifically we show that the infrared divergent part of the two-loop am…
