Abstract
The latest measurement of the muon g-2 announced at Fermilab exhibits a large discrepancy from the currently accepted Standard Model prediction. The primary source of uncertainty on the theoretical value is represented by the leading order hadronic contribution (a_HLO), traditionally determined through a data-driven dispersive approach. An independent crosscheck of a_HLO is essential to understand this tension and consolidate the theoretical prediction.
The MUonE experiment proposes a novel approach to determine a_HLO by measuring the running of the electromagnetic coupling constant via muon-electron elastic scattering in the space-like region. The measurement will be performed using a 160 GeV muon beam at CERN . The experimental principle, hardware and software developments and the status of the test runs will be introduced in this talk.
Series This talk is part of the Cavendish HEP Seminars series.
