Description

Mu3e is a novel experiment designed to probe for lepton flavor violation in the muon decay into three electrons. Its goal is to improve the current experimental limit by four orders of magnitude and reach a sensitivity of 1 in ${10}^{16}$ muon decays. The foreseen stopping rate of ${10}^8$ muons/s generate combinatorial background which could only be rejected by precise time information. A detector consisting of staggered $250\mu m$ scintillating fibers readout by silicon photomultiplier arrays will discriminate piled up particles with a time resolution of less than a nanosecond. An overview of the design, followed by recent performance results and status of the detector will be presented.
