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.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
