Abstract
We apply a simple extension of the gluon-fusion model of Einhorn and Ellis to the photoproduction of charmed particles at high energies. Overall rates of production are not much different from those predicted by various current models for strong production of charm, leading to the belief that charm should be more easily seen in the photoproduction case where background are smaller. The predictions of the model for various energy and angle distributions are presented. Predicted rates depend strongly on the mass of the charmed quark.
