Next-to-leading order corrections to heavy flavor production in longitudinally polarized photon-nucleon collisions - art. no. 114509

A complete next-to-leading order calculation of longitudinally polarized he avy quark photoproduction is presented. All results of the perturbative cal culation are given in detail. For reactions and energies of interest cross sections differential in the transverse momentum and rapidity of the heavy quark, total cross sections, and the corresponding asymmetries are given. E rrors in the asymmetries are estimated and the possibility to distinguish b etween various scenarios of the polarized gluon distribution is discussed. Our results are compared with other related publications.
