“…As compared to other methods suggested in the literature, reconstruction approximants don't require extra input from either phenomenological estimates or LQCD evaluations. This gives the possibility that a MUonE experiment [32,33] may provide a totally independent result from either the dispersive evaluations in refs. [7,8] or the LQCD determination of ref.…”

The MUonE proposal at the CERN SPS consists in extracting the value of the hadronic vacuum polarization self-energy function (HVP) from its contribution to the differential cross-section of elastic muon-electron scattering. The HVP contribution to the muon anomalous magnetic moment can then be obtained from a weighted integral of the measured HVP self-energy function. This, however, requires a knowledge of the HVP function in its full integration domain. This paper discusses a procedure to reconstruct the HVP function in the regions not directly accessible to measurement. The method is based on the so-called transfer theorems, due to Flajolet and Odlyzko, which we explain and adapt to HVP.

“…Recent progress, after the experimental proposal [14], in the study of the main systematics and in the development of the experimental apparatus and data analysis strategies have been documented in Refs. [15,16,17,18,19,20]. On the theory side several groups have already reached important milestones related to next-to-next-to-leading QED radiative corrections and their implementation in independent MC codes [21,22,23,24,25,26,27,28,29].…”

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 muonelectron scattering at relatively small momentum transfer. The anticipated accuracy of the order of 10ppm demands for high-precision prediction in radiative corrections to the µe scattering as well as for robust quantitative estimates of all possible background processes. In this letter, the contribution due to the emission of a neutral pion through the process µe → µeπ 0 is studied and its numerical impact is discussed in different phase space configurations by means of the upgraded Monte Carlo event generator MESMER. In fact, single π 0 production could be a source of reducible background for the measurement of the QED running coupling constant at MUonE and it could be also an important background for possible New Physics searches at MUonE involving 2 → 3 processes, in phase space regions complementary to the ones characteristic of the elastic µe scattering.
