  At the LHC, the processes with several particles in the final state occur
routinely. These processes provide a new domain to test the Standard Model of
particle physics. Due to large gluon luminosity at the LHC, gluon initiated
processes will be quite important. We study the production of multi-vector
bosons via gluon fusion. In particular we consider the process $ g g \to g
\gamma Z $ and compute its cross-section at hadron colliders.
