摘要：

We estimate the cross section for gamma p --> Y p by two independent methods. First, by studying the corrections to the naive leading-order QCD formula and, second, by using parton-hadron duality. The estimates are in good agreement with each other and with the recent measurements of the cross section at HERA. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
