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 for the space-time dimension tending to the physical value . As the result of a remarkable cancellation the third order pole in disappears in the trajectory and the expansion starts with .
