Charm Photoproduction At Large Transverse Momentum And The Charm Content Of The Photon
Abstract
Description
The charm quark photoproduction at large transverse momentum in the resolved photon interaction via partonic subprocess $\cg$ is studied. It is shown that at HERA energies the contribution of the charm quark excitation in the photon in the inclusive charm production at $\pt>5$ GeV/c dominates over the other resolved photon contribution via the gluon content of the photon and it is about 30\% of the contribution of the $c\bar c$-pair production via the photon-gluon fusion mechanism.
