Description

The Mu3e experiment will search for the lepton flavor violating neutrinoless muon decay $\mu^+ \rightarrow e^+ e^- e^+$ with a sensitivity down to $10^{-16}$ (90 % C.L.), i.e. a four order of magnitude improvement over previous measurements, using the world most intense muon beam at the Paul Scherrer Institute. This decay is strongly suppressed in the Standard Model, whilst several Beyond the SM models predict observable effects accessible to the new generation of LFV experiments. The search for the $\mu^+ \rightarrow e^+ e^- e^+$ decay requires a large acceptance detector capable of coping with rates of up to $2 \times 10^9$ stopped muons per second with excellent momentum, spacial, and time resolution to suppress backgrounds below the $10^{16}$ level. The required Mu3e detector performance is possible thanks to tracking detectors based on thin monolithic active silicon pixel sensors (HV-MAPS) in conjunction with an innovative tracking concept and very precise timing measurements using scintillating fibers and tiles coupled to silicon photo-multipliers. The first phase of the Mu3e exeriment aiming to a sensitivity of $10^{-15}$ has been recently approved. Following the R&D phase, the collaboration is currently preparing for detector construction. First data taking is expected in 2017.
