Description
Lepton Flavor Violation (LFV) is strongly suppressed in the Standard Model, whilst several models based on {\it new physics} predict observable effects accessible to the new generation of experiments. Mu3e will search for the LFV neutrinoless muon decay μ+→e+e−e+ with a sensitivity down to 10−16 (at 90\% C.L.) using the world most intense continuous muon beam at the Paul Scherrer Institute.
The search for the μ+→e+e−e+ decay requires a large acceptance detector capable of coping with rates of up to 2×109 stopped muons per second with excellent momentum, spacial, and time resolution. The Mu3e detectoris based on thin monolithic active silicon pixel sensors (HV-MAPS) for precise tracking in conjunction with scintillating fibers and tiles coupled to Si-PMs arrays for very precise timing measurements. After an intense R\&D phase, the Mu3e apparatus is under constructions. First data is expected in 2020.
