Abstract

It is argued that photoproduction of charmed particles can be considered within the same theoretical framework as deep inelastic scattering off the usual hadrons. The role of large Q² now plays the charmed quark mass m_c². In particular, the standard technique of the moments from the structure functions is applicable. In this way we get a sum rule which relates an integral from the charmed particles photoproduction cross section to the heavy quark mass and effective coupling constant of strong interactions.
