Abstract

It is demonstrated that the differences between leading and higher order QCD predictions forF 2 γ (x, Q2) are too small to be distinguished by present experiments. Similarly to the well known case of deep inelastic lepton-nucleon scattering, the hadronic (non-perturbative) photonic input parton distributions atQ2=Q 0 2 have to be different for the LO and HO calculations.
