Abstract

Abstract By introducing, in a covariant way, explicit polarization vectors for the gluons, we calculate the various helicity amplitudes for the processes g+ g→( 2S+1 L J)+ g, with L = S or P . In this way, we obtain simple formulae for the cross sections of these processes, which, in the framework of the perturbative QCD, are related to the hadroproduction of heavy quarkonia.
