Hadronic component of the photon spin-dependent structure function g₁^γ from QCD

Research output: Contribution to journal › Article › peer-review

Abstract

We calculate the spin-dependent structure function of the polarized virtual photon g₁^γ(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.
