Description
The MUonE experiment at CERN aims to provide an independent measurement of the leading-order hadronic contribution to the muon g-2 ($a_{\mu}^\text{HVP}$), complementary to the existing ones. The innovative approach proposed by MUonE is based on the measurement of the hadronic contribution to the running of the QED coupling, which can be extracted from a precise measurement of the shape of the differential cross section of the $\mu\!-\!e$ elastic scattering.
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. The M2 beam line provides the necessary intensity needed to reach the statistical goal in few years of data taking. The experimental challenge relies in the precise control of the systematic effects. A first run with a minimal prototype detector was carried out in 2023, while a pilot run including a reduced setup of the full detector components is ongoing in Summer 2025. The status of the experiment will be presented, along with first preliminary results from the 2025 run and the future plans.
