Twist-3 Effects in Polarized Photon Structure

Abstract

The polarized photon structure is described by two spin structure functions $g_1^{\gamma }$ and $g_2^{\gamma }$ which can be studied in the future polarized ep or e${}^{+}$e${}^{-}$ colliders. Here we investigate the QCD twist-3 effects in $g_2^{\gamma }$ to the leading order in QCD.
