The Mu2e experiment at Fermilab

The Mu2e experiment searches for the neutrinoless muon to electron conversion in the field of a nucleus, which is a charged lepton flavor violating process. The goal of the experiment is to reach a single event sensitivity of 2.8×10⁻¹⁷, setting an upper limit on the muon conversion rate of 6.7 × 10⁻¹⁷. This corresponds to a four order of magnitude improvement with respect to the existing limits.
