Description

The structure functions of a real photon are calculable in QCD. The leading contribution is proportional to 1n Q2, with a coefficient reflecting the gluon flux in a real photon. We investigate this leading term for non-zero target photon mass. In an appropriate limit the gluon content in a virtual photon is found to vanish. The gluon radiative corrections of QCD can thus be turned off by tuning the target photon mass. (orig.)
