The high energy limit of QCD is investigated in the generalized leadinglogarithmic approximation. We study unitarity corrections to the BFKL Pomeroncontaining t-channel states with up to six gluons. Special attention is givento the field theory structure of the corresponding multi-gluon amplitudes. Wediscuss the transition from two to six gluons in the t-channel.Comment: 67 pages, many figure
