Abstract
We discuss the production of γγ and Z0γ pairs induced by the gluon-gluon fusion mechanism at typical supercollider energies. Due to the large flux of gluons with small fractional momenta, it is found that in certain kinematical configurations this subprocess, although of order (αs/π)2 with respect to the leading quark annihilation, can give an appreciable contribution to the cross section for Z0γ production and even a larger one for the γγ production.File in questo prodotto:
