Quark scattering amplitudes at strong coupling

Abstract

Following Alday and Maldacena [1], we describe a string theory method to compute the strong coupling behavior of the scattering amplitudes of quarks and gluons in planar = 2 super Yang-Mills theory in the probe approximation. Explicit predictions for these quantities can be constructed using the all-orders planar gluon scattering amplitudes of = 4 super Yang-Mills due to Bern, Dixon and Smirnov [2].
