A Novel Experiment to Search for the Decay μ→ eee

Design studies for an experiment searching for the lepton flavor violating decay μ→ eee are presented. The detector concept is based on thin layers of silicon sensors with fast readout. The aim of this experiment is to reach a sensitivity of B(μ→ eee) ≈ 10-16 corresponding to an improvement by a factor 10000 compared to previous experiments.
