Search for the lepton-flavour violating decay
μ+→e+e+e−


The Mu3e experiment is a new search for the lepton-flavour violating decay of a positive muon into two positrons and one electron. See here for a an overview of the experiment.

Mu3e detector being craned

Mu3e craned into the magnet for June test run

Today the Mu3e detector was craned from the statging area to the piE5 beam area, where we plan to take beam with final detector elements from all three subdetectors in June. - With video!
