Hard two photon processes \gamma\gamma --> M_2 M_1 in QCD

Abstract

A short review of leading term QCD predictions vs those of the handbag model for large angle cross sections \gamma\gamma --> P_2 P_1 (P is the pseudoscalar meson \pi^{\pm,o}, K^{\pm,o}, \eta), and for \gamma\gamma --> V_2 V_1 (V is the neutral vector meson \rho^o, \omega, \phi), in comparison with Belle Collaboration measuments
