Gluon induced contributions to Z gamma production at hadron colliders
arXiv:hep-ph/0211295 · doi:10.1103/PhysRevD.67.034016
Abstract
We study the contribution of gluon induced partonic subprocesses to Z gamma pair production at hadron colliders. These processes contribute only at next-to-next-to-leading order but are potentially enhanced by two factors of the gluon parton densities. However, we find that their contribution is modest and that next-to-leading order calculations give reliable predictions.
