Production of $γZ g$ and associated processes via gluon fusion at
hadron colliders    [PDF]

Pankaj Agrawal, Ambresh Shivaji

We present phenomenological results for the process $gg \to \gamma Z g$ within the standard model at hadron colliders. Due to large gluon flux at the LHC and the proposed HE-LHC, this process can have significant cross section at these machines. Several thousand such events have already been produced at the LHC. This process can also be a background to new physics signals. We compute its cross section at the hadron colliders and give some important kinematic distributions. We discuss some of the important features of this process. The detailed results are presented for 8 and 14 TeV center-of-mass energies. We also briefly discuss the production of $\gamma \gamma g $ and $\gamma \gamma Z$ via gluon fusion. The amplitude of these processes are closely related to the $gg \to\gamma Z g$ amplitude.
