Spin structure function of the virtual photon

High Energy Physics - Phenomenology 2009-10-31 v1

Abstract

We investigate the spin structure of the virtual photon beyond the leading order in QCD. The first moment of the virtual photon spin structure function g1γ(x,Q2,P2)g_1^\gamma(x,Q^2,P^2) with QCD effects turns out to be non-vanishing in contrast to the real photon case. Numerical analysis for virtual as well as real photon case is presented.
