摘要：
We consider the multi-Regge limit for N=4 SYM NMHV leading color amplitudes in two different formulations: the BFKL formalism for multi-Regge amplitudes in leading logarithm approximation, and super conformal N=4 SYM amplitudes. It is shown that the two approaches agree to two-loops for the 2 -> 4 and 3 -> 3 six-point amplitudes. Predictions are made for the multi-Regge limit of three loop 2 -> 4 and 3 -> 3 NMHV amplitudes, as well as a particular sub-set of two loop 2 -> 2 + n (NMHV)-M-k amplitudes in the multi-Regge limit in the leading logarithm approximation from the BFKL, point of view.
