A bstract The recently proposed MUonE experiment at CERN aims providing a novel determination of the leading order hadronic contribution to muon anomalous magnetic moment through study elastic muon-electron scattering relatively small momentum transfer. anticipated accuracy 10ppm demands for high-precision predictions, including all relevant radiative corrections. fixed-order NNLO corrections due emission virtual and real leptonic pairs are described their numerical impact is discussed typical event selections experiment, by means upgraded Monte Carlo code M esmer .
