Gluon Regge Trajectory in the two-loop Approximation

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

Evaluating two-loop integrals in the transverse momentum space we obtain the trajectory of the Reggeized gluon in QCD in an explicit form in the two-loop approximation. It is presented as an expansion in powers of (D4)(D-4) for the space-time dimension DD tending to the physical value D=4D=4. As the result of a remarkable cancellation the third order pole inD4D-4 disappears in the trajectory and the expansion starts with (D4)2(D-4)^{-2}.
