The Bethe roots of Regge cuts in strongly coupled N = 4 SYM theory

Abstract

Abstract: We describe a general algorithm for the computation of the remainder function for n-gluon scattering in multi-Regge kinematics for strongly coupled planar N=4$$ \mathcal{N}=4 $$ super Yang-Mills theory. This regime is accessible through the infrared physics of an auxiliary quantum integrable system describing strings in AdS5×S5. Explicit formulas are presented for n = 6 and n = 7 external gluons. Our results are consistent with expectations from perturbative gauge theory. This paper comprises the technical details for the results announced in [1].
