### Event details

Title:

Muon-Electron scattering at 10ppm for MUonE

Abstract:

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.
