Abstract We employ the LuxQED approach to compute the polarized photon PDF (photon pPDF). This approach expresses the pPDF in terms of the structure functions $$g_1$$ g 1 and $$g_2$$ g 2 . Different models for the structure functions are employed acc

Abstract We discuss the effect of QED corrections in the evolution of polarized parton distributions. We solve the corresponding evolution equations exactly to $${\mathcal {O}}(\alpha )$$ O ( α ) and $${\mathcal {O}}(a_{\textrm{S}}^2)$$ O ( a S 2 )
