Gluon distributions in real and virtual photons are calculated using evolution equations in the NLO approximation. The quark distributions in the photon determined on the basis of the QCD sum rule approach in ref.[1] are taken as an input. It is shown that gluon distribution in the photon can be reliably determined up to x = 0.03 ÷ 0.05 much lower than the… (More)
