Gluon induced contributions to Z γ production at hadron colliders
We study the contribution of gluon induced partonic subprocesses to Zγ 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 a...

| Sumario: | We study the contribution of gluon induced partonic subprocesses to Zγ 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. © 2003 The American Physical Society. |
