| Popis: | The recently proposed MUonE experiment at CERN aims at providing a novel determination of the leading order hadronic contribution to the muon anomalous magnetic moment through the study of elastic muon-electron scattering at relatively small momentum transfer. The anticipated accuracy of the order of 10ppm demands for high-precision predictions, including all the relevant radiative corrections. The fixed-order NNLO radiative corrections due to the emission of virtual and real leptonic pairs are described and their numerical impact is discussed for typical event selections of the MUonE experiment, by means of the upgraded Monte Carlo code MESMER. Comment: 35 pages, 26 figures. A Mathematica ancillary file for MIs discussed in Appendix A is provided. Updated to the published version: one reference added, some details added at the end of Section 4, few typos corrected, conclusions unchanged |
