Abstract
The production cross sections of to a heavy quarkonium with -parity even wave and wave associated with a photon are analyzed in the framework of non-relativistic Quantum Chromodynamics(NRQCD) factorization formalism. The short-distance coefficients are determined up to the next-to-leading order(NLO) QCD radiative corrections for and wave and NLO relativistic corrections for wave in analytical forms. Applying the results to estimate the cross sections we find that both the radiative and relativistic corrections are considerable.
