We have investigate the production of lepton and pseudoscalar meson charged pairs by high energy linearly polarized photon-proton scattering in the point-like approximation. The corresponding azimuthal and polar angle distributions on a recoil proton in the inclusive experimental setup have been calculated. The asymmetry Ltot has the values from 0.02 at small values of the polar angle q up to 0.05 for q ~ p/2.
