Description

The MUonE experiment aims at a competitive determination of the leading hadronic contribution to the muon anomalous magnetic moment, completely independent from the other existing results.
It could have a crucial role to clarify the comparison of the $a_{\mu }$ measurement with the Standard Model, given the recent Fermilab result, and the tension between the accepted theory prediction and a new Lattice QCD calculation.
The novel method requires a precise measurement of the hadronic component of the running electromagnetic coupling, which can be extracted from the shape of the differential cross section of $\mu e$ elastic scattering, obtained by the 160 GeV CERN muon beam on fixed target.
The project status is presented, in view of the test run on a reduced detector, which is starting in Fall 2021 and will be completed in 2022.
