Hadronic component of the photon spin-dependent structure function g1γ from QCD

Research output: Contribution to journalArticle

Abstract

We calculate the spin-dependent structure function of the polarized virtual photon g1γ(x, Q2, p2), especially its hadronic part, using the operator product expansion (OPE) in the inverse powers of the target photon virtuality. Some model is accepted to achieve a correct analytical behaviour in the photon squared mass. This enables extrapolation to the case of a real photon.
