The Mu3e experiment searches for the ultra-rare decay of a muon into three electrons. In the standard model, this charged lepton flavor changing decay is suppressed well below 10^-50. With innovative detector technology we are going to challenge the current best upper limit of 10^-12 by four orders of magnitude. We are currently constructing a pixel detector using HV-MAPS, thinned down to 50 µm. With this we reach a radiation length of the order of one permille per detector layer. The cooling is done with gaseous helium. Scintillators are used for precision timing and no hardware trigger can be used. I’m going to show you the physics motivation and how this translates into the detector requirements.
