Perturbative QCD analysis of near threshold heavy quarkonium photoproduction at large momentum transfer
We apply perturbative QCD to investigate the near threshold heavy quarkonium photoproduction at large momentum transfer. From an explicit calculation, we show that the conventional power counting method will be modified and the three quark Fock state with nonzero orbital angular momentum dominates t...
