      We investigate the asymmetries arising due to electromagnetic interactions in largePT pion inclusive processes. The hardqcd processes that contribute to such asymmetries areq+gq+γ,q+qg+γ etc. which are suspected to be substantial, as indicated by theqcd predictions for a significant and increasingγ/πo ratio at largePT. We calculate the expected isospin related asymmetries and propose tests that might detect them. Our estimates indicate that the effects are much smaller than may be naively expected. We also observe a remarkable scaling of asymmetries in the variablePT/(s)1/2.
