The Spin Structure of a Polarized Photon

High Energy Physics - Phenomenology 2009-09-11 v1

Abstract

We show that the first moment of the spin-dependent structure function g1γ(x,Q2)g_1^{\gamma}(x,Q^2) of a real photon vanishes independent of the momentum transfer Q2Q^2 it is probed with. This result is non-perturbative: it holds to all orders in perturbation theory in abelian and non-abelian gauge theory and at every twist.
