Effect of triple gluon coupling in semi-inclusive polarized scattering processes

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We show that the gluon helicity inside a proton and a photon can be deduced from a knowledge of a special combination of cross sections of the semi-inclusive processese+p→e+π+π+... ande ++e −→e ++e −+π+π+... Such a measurement could thus be used to check the QCD prediction that the gluon helicity increases linearly with lnQ 2.
