Searches for New Physics with the Mu3e Experiment — •Ann-Kathrin Perrevoort for the Mu3e collaboration — Physikalisches Institut, Universität Heidelberg
The upcoming Mu3e experiment searches for physics beyond the Standard Model in the lepton-flavour violating decay µ+→ e+ e+ e− with a final sensitivity of one signal decay in 1016 muon decays. For this purpose, the detector is designed to measure electron and positron tracks of low momenta with excellent precision while operating at very high muon stopping rates in the order of 108µ/s up to 109µ/s.
The high number of observed muon decays combined with the excellent detector resolution opens up a window for New Physics searches beyond the µ→ eee decay. Currently, two classes of such processes are under study. These are processes of the type µ+→ e+X0 with X0 being a neutral light boson, as well as µ+→ e+Aν_µνe, where the A can either decay to an e+ e− pair or leave the detector unseen. An example of A could be a dark photon.
Simulation studies estimating the sensitivity of the Mu3e experiment to these processes will be presented.
