摘要：

We investigate small-x resummation effects in QCD coefficient functions for Z(0)g and Wg fusion processes, and we compare them with the known ones of gamma g type. We find a strong process dependence that we argue to be due to the possible presence of collinear singularities for either small or large k of the exchanged gluon. For top quark production, we find that the gg --> t (t) over bar and Z(0)g --> t (t) over bar channels have larger resummation enhancements than the Wg --> t (b) over bar one.
