Highenergy amplitudes in N = 4 SYM in the nexttoleading order
Abstract
In this study, the highenergy behavior of the N = 4 SYM amplitudes in the Regge limit can be calculated order by order in perturbation theory using the highenergy operator expansion in Wilson lines. At large $$N_c$$, a typical fourpoint amplitude is determined by a single BFKL pomeron. The conformal structure of the fourpoint amplitude is fixed in terms of two functions: pomeron intercept and the coefficient function in front of the pomeron (the product of two residues). The pomeron intercept is universal while the coefficient function depends on the correlator in question. The intercept is known in the first two orders in coupling constant: BFKL intercept and NLO BFKL intercept calculated in Ref. 1. As an example of using the Wilsonline OPE, we calculate the coefficient function in front of the pomeron for the correlator of four $Z^2$ currents in the first two orders in perturbation theory.
