Abstract
The latest measurement of the muon g-2, recently announced at Fermilab, exhibits a 4.2σ discrepancy from the Standard Model prediction. The hadronic contribution aμHLO represents the main source of uncertainty on the theoretical prediction. The MUonE experiment proposes a novel approach to determine aμHLO by measuring the effective electromagnetic coupling in the space-like region, via μ−e elastic scattering. The measurement is performed by scattering a 160 GeV muon beam, available at CERN, on atomic electrons of a low-Z target. A Test Run on a reduced detector is planned in 2022, to validate this proposal. The status of the experiment in view of the Test Run is presented.
