Description
We demonstrate Reggeization associated with Glauber gluon exchanges in the strict collinear factorization violating pieces in the space-like splitting amplitudes featuring aspects of both forward and hard scattering. We find that by exploiting contour deformation away from the Glauber region wherever possible the collinear subgraphs defined in the effective theory can be computed without requiring a non-analytic regulator. Thus, a challenging two-loop computation is reduced to a handful of significantly simpler one-loop subgraphs. Our work is aided with development of new software tools initiating a systematic study of processes involving Glauber exchanges at a multi-loop level.
