Photoproduction of J/$\psi$ in the forward region

We study the phenomenology of fixed-target elastic J/{psi} photoproduction in the nonrelativistic QCD (NRQCD) factorization formalism. Our goal is to test an essential feature of this formalism{emdash}the color-octet mechanism. We obtain an order-of-magnitude estimate for a certain linear combination of NRQCD color-octet matrix elements. Our estimate is consistent with other empirical determinations and with the v-scaling rules of NRQCD. {copyright} {ital 1997} {ital The American Physical Society}
