Some properties of the Alday-Maldacena minimum

Abstract

The Alday-Maldacena solution, relevant to the n = 4 gluon amplitude in N = 4 SYM at strong coupling, was recently identified as a minimum of the regularized action in the moduli space of solutions of the AdS5 σ-model equations of motion. Analogous solutions of the Nambu-Goto equations for the n = 4 case are presented and shown to form (modulo the… (More)
