Implications of multi-Regge limits for the Bern-Dixon-Smirnov conjecture

Planar N = 4 super Yang-Mills SU(N) theory is expected to exhibit stringy behavior, anticipated by the 't Hooft genus expansion and the AdS/CFT correspondence. We examine the Bern-Dixon-Smirnov (BDS) conjecture for n-gluon amplitudes in the context of single-Regge and multi-Regge limits and show that these amplitudes have the expected Regge form in the Euclidean region.
