NLO Corrections to Heavy Quark Production with Polarized Beams
Abstract
We present a calculation of the NLO QCD corrections to heavy flavor photoproduction with longitudinally polarized beams. We apply our results to study the spin asymmetry for total charm quark production which will be used for a first direct determination of Delta g by the COMPASS experiment. We also briefly discuss the main theoretical uncertainties inherent in this calculation.
