A phenomenological model which has had some success in explaining polarization phenomena and left-right asymmetry in inclusive proton-proton scattering is considered for reactions involving photons. In particular,the reactions (a) γ + p → H + X; (b) γ + p(↑) → π± + X and (c) p(↑) + p → γ + X are considered where γ = resolved photon and hyperon H = Λ, Σ, Ξ etc. Predictions for hyperon polarization in (a) and the asymmetry (in (b) and (c)) provide further tests of this particular model. Feasibility of observing (b) at the acce;erators the effect of the polarization of the sea in the proton in p(↑) + p → π± + X is briefly discussed. We also see the possibility of these effects in leptons (including neutrinos)
