 note = {We investigate the one-gluon-exchange (  s) corrections to the real photon structure functions WTT,WLT, WaTT and W TT in the massive parton model.We employ a technique based on the Cutkosky rules andthe reduction of Feynman integrals to master integrals. We show that a positivity constraint, which isderived from the Cauchy-Schwarz inequality, is satisfied among the unpolarized and polarized structurefunctions WTT, WaTT and W TT calculated up to the next-to-leading order in QCD.},
