PHOTOPRODUCTION OF H(C) - ART. NO. 037503

Using the NRQCD factorization formalism, we calculate the total cross section for the photoproduction of h(c) mesons. We include color-octet and color-singlet mechanisms as well as next-to-leading order perturb ative QCD corrections. The theoretical prediction depends on two nonpe rturbative matrix elements that are not well determined from existing data on charmonium production. For reasonable values of these matrix e lements, the cross section is large enough that the h(c) may be observ able at the E831 experiment and at the DESY HERA experiments. [S0556-2 821(98)00617-1].
