The MUonE experiment

The MUonE experiment aims to determine the hadronic leadingorder contribution to the muon anomalous magnetic moment from a measurement of the effective QED coupling constant at space-like momenta, using muon-electron elastic scattering within CERN accelerator complex. This method is complementary to the traditional one and completely innovative. Its challenge resides in the control of the theoretical and experimental systematics at 10−5, an unprecedented precision level for a scattering experiment. This proposal has been submitted to the Physics Beyond Colliders committee at CERN.
