Abstract

Abstract: Mu3e is an experiment searching for charged lepton flavour violation in the decay μ + → e + e − e + . Decay vertex position, decay time and particle momenta have to be precisely measured in order to reject both accidental and physics background. A silicon pixel tracker based on 50 μm thin High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) in a 1 T magnetic field provides precise vertex and momentum information. A scintillating fibre detector and a scintillating tile detector provide sub-nanosecond time information. The status of the Mu3e detector is presented, summarizing the development of HV-MAPS chips, the pixel detector modules as well as the timing detectors.
