G. Grispos et al., Polarized photoproduction of large-p(T) hadron pairs as a probe of the polarized gluon distribution - art. no. 014023, PHYS REV D, 6201(1), 2000, pp. 4023
Production of large-p(T) hadron pairs by a polarized photon on a longitudin
ally polarized proton towards probing the polarized gluon distribution is s
tudied. Resolved photon contributions and the effect of changing the scales
are taken into account, and predictions are presented. A very recent exper
imental result at c.m. energy 7.18 GeV is compared to our predictions exten
ded down to this energy. A proper combination of cross sections is also con
sidered.
