Abstract

The virtual photon structure function g₁^γ(x,Q²,P²), which can be obtained in polarized e⁺e^- colliding-beam experiments, is investigated for Λ² ≪ P² ≪ Q², where -Q² (-P²) is the mass squared of the probe (target) photon. The analysis is made to next-to-leading order in QCD, in the framework of the QCD improved parton model with the DGLAP evolution equations. The non-leading corrections significantly modify the leading log result, in particular, at large x as well as at small x.
