The Mu2e experiment at Fermilab: a search for lepton flavor violation

The Mu2e experiment at Fermilab will search for the charged lepton flavor violating process of neutrino-less μ→e coherent conversion in the field of an aluminum nucleus. About 7 ⋅ 1017 muons, provided by a dedicated muon beam line in construction at Fermilab, will be stopped in 3 years in the aluminum target. The corresponding single event sensitivity will be 2.5⋅10−17. In this paper a brief overview of the physics explored by the μ→e conversion is given, followed by a description of the Mu2e experimental apparatus and the expected detector performance.
