MUonE experiment

The anomalous magnetic moment of the muon has been a long stand ing issue in the field of particle physics. The recent results by Fermilab have pointed to a possible discrepancy of 4.2σ with respect to the Standard Model prediction. Although the future measurements will undoubtedly strengthen this result, the large uncertainty of the prediction, caused by a non-perturbative hadronic contribution, remains an issue. The MUonE experiment is designed to provide an independent, precise measurement of this contribution by employ ing a series of tracking stations and low-Z targets, to precisely determine the shape of differential cross-section of an elastic µ + e → µ + e scattering. It is expected to increase the result’s significance to at least 7σ, thus solidifying the discovery. The design of the detector allows also for New Physics searches with a signature of displaced vertices.
