Description
The MUonE experiment, now under development at CERN, aims to determine the leading-order hadronic vacuum polarization contribution to the muon's anomalous magnetic moment via a new, independent method. Similar hadronic effects contribute to the running of the QED coupling $\alpha$, which can be extracted from a precise measurement of the shape of the differential cross section for elastic scattering of high-energy muons from atomic electrons in a low-Z target. A Phase 1 test run of the experiment was completed in summer 2025, with the goals of confirming the leptonic part of the running of $\alpha$ and making a first measurement of the hadronic part with $\cal O$(20%) statistical accuracy. We will present the first preliminary results from this run and discuss the future plans.
