Abstract
We present an analytical solution for the evolution of parton distributions incorporating mixed-order QCD QED corrections, addressing both polarized and unpolarized cases. Using the Altarelli-Parisi kernels extended to mixed order, we solve the DGLAP equations exactly in Mellin -space and derive the associated Wilson coefficients for the polarized structure function . Our analytical approach improves computational efficiency and enhances the precision of theoretical predictions in observables sensitive to QED corrections, with relevance for current and future phenomenological applications.
