Muon-Electron scattering at 10ppm for MUonE

Aula Marchetti (U1-07) (University of Milan-Bicocca)

The MUonE experiment aims at extracting the hadronic vacuum polarisation through a precise measurement of muon-electron scattering. This novel approach will shed light on the current disagreement between the traditional dispersive determination and lattice computations, resulting in different predictions for the muon g-2. However, a competitive extraction with MUonE requires a fully-differential calculation of muon-electron scattering at the level of 10ppm. I will present our efforts in the McMule team to achieve this level of precision. An emphasis will be put on the methods that we have developed for this type of calculation: the infrared subtraction scheme, massification, and next-to-soft stabilisation. After presenting our current results, I will talk about the possibility of going beyond NNLO.
