摘要：

As for nucleons, the high energy hadronic interactions of photons are determined by their gluon structure. Previous strategies for making a first measurement of the gluon distribution function of the photon at HERA suffer from backgrounds from processes where the photon interacts as a point particle or via its quark structure. We show that these three contributions can be separated by combining luminosity monitor information on the recoil electron with information from the main detector in the case of jet, heavy quark, or psi-events.
