Description
We address the computation of the four-point function of R-currents in N=4 SYM in the
Regge limit as a tool to study such regime in a gauge invariant framework. The
R-current is a close analog of the EM current in QED and SQED, which couple a gauge
invariant state ('photon') to a YM system. Gauge invariance guarantee that the
amplitude is free from infrared divergences. We discuss some subtlelties associated
with the fact the R-current are not associated with a gauge symmetry.
