The latest measurement of the muon g-2, performed by the Muon g-2 Collaboration at Fermilab, presently exhibits a 4.2σ discrepancy from the Standard Model prediction. The hadronic contribution aHLO μ represents the main source of uncertainty on the theoretical prediction. The MUonE experiment proposes a novel approach to determine aHLO μ by measuring the running of the electromagnetic coupling constant in the space-like region, via μ−e elastic scattering. The measurement will be performed by scattering a 160 GeV muon beam, currently available at CERN’s North Area, on the atomic electrons of a low-Z target. A Test Run on a reduced detector is planned to validate this proposal. The status of the experiment in view of the Test Run will be presented.
