Nonforward color-octet kernel of the Balitsky-Fadin-Kuraev-Lipatov equation

Abstract

The contribution to the kernel of the nonforward Balitsky-Fadin-Kuraev-Lipatov equation from two-gluon production is calculated for the case of the antisymmetric color-octet state of two Reggeized gluons in the t channel. The one-gluon contribution to the kernel in the one-loop approximation is also obtained by using the one-loop expression for the effective vertex of the one-gluon production in Reggeon-Reggeon collisions. An explicit form of the total kernel is presented.
