Special colloquium: The MUonE experiment: an alternative method to measure the hadronic contribution to the muon g-2

compelling observables to test the validity of the Standard Model and its possible extensions. The Muon g-2 experiment at Fermilab has recently published its final measurement of a_μ with the astonishing precision [...] consolidate the theoretical prediction, in order to fully exploit the discovery potential of the muon g-2. The MUonE experiment aims to shed light on this critical discrepancy by measuring a_μ^{HVP,LO} with [...] measurement of the shape of the μ+e−→μ+e− differential cross section. The experiment is carried out at the M2 beam line at CERN, where a 160 GeV muon beam is scattered off the atomic electrons of a low-Z target …
