### Description

The MUonE experiment aims at an independent and competitive determination of the leading hadronic contribution to the muon anomalous magnetic moment $a_\mu = (g_\mu -2)/2$, based on an alternative method, complementary to the existing ones. It relies on the measurement of the shape of the $\mu e$ elastic scattering cross section, with unprecedented precision, which can be obtained at CERN by exploiting the available 160 GeV muon beam in fixed target collisions.
MUonE 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.
A Test Run with a reduced detector is planned to validate the proposal. The status of the experiment and the future plans will be presented.
