Description
We study higher order relativistic corrections to the electromagnetic production cross-section of a heavy quarkonium and a hard photon in the factorization framework of non-relativistic QCD (NRQCD). We obtain new matching coefficients and discuss the importance of contributions from color octet operators, that were not considered in the previous studies of this process.
