Abstract
We study the phenomenology of fixed-target elastic J/psi photoproducti on in the nonrelativistic QCD (NRQCD) factorization formalism. Our goa l is to test an essential feature of this formalism-the color-octet me chanism. We obtain an order-of-magnitude estimate for a certain linear combination of NRQCD color-octet matrix elements. Our estimate is con sistent with other empirical determinations and with the upsilon-scali ng rules of NRQCD.
