Sum Rules of Polarized Photon Structure Functions Revisited

K. Sasaki, T. Ueda, T. Uematsu

The target mass dependence of the sum rule for the polarized virtual photon structure function g1\gamma (x,Q2,P2) is studied when P2, the mass squared of the target photon, changes from on-shell to far off-shell. Also the sum rule for another polarized structure function g2\gamma (x,Q2,P2) is analyzed in Parton Model (PM). It is found that the first moment of g2\gamma calculated in PM vanishes independent of Q2, P2 and quark mass.
