Gluon Regge trajectory in the two-loop approximation

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 (D − 4) for the space-time dimension D tending to the physical value D = 4. As the result of a remarkable cancellation the third order pole in D − 4 disappears in the trajectory and the expansion starts with (D − 4)−2.
