Polarized Deep Inelastic Scattering

We discuss the polarized photon structure function [Formula: see text] and focus on the first moment of [Formula: see text], where we explore the role of the axial QED and strong U(1) anomalies. Electromagnetic gauge invariance determines an exact sum rule for the first moment of [Formula: see text]. If we accept a recently proposed definition of “spin content” then we must also accept a polarized gluon component of Δgγ=2π/αs in the spin-one photon.
