Abstract

Amplitudes are derived for the quantum-chromodynamic subprocess γ g → ( J ψ ) g , with a specific wave function used to represent the J ψ as a c c ¯ system. The results are used to obtain the normalized total cross section σ γ for the inelastic process γ N → ( J ψ ) X , predictions for the z and p T dependence of inelastic J ψ photoproduction, and predictions for the J ψ helicity. The predictions apply as well to electroproduction at small Q 2 .
