  The Mu2e experiment searches for the neutrino-less 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 x 10^{-17}, setting an upper limit on the muon conversion
rate at 6.7 x 10^{-17}. This corresponds to a four order of magnitude
improvement with respect to the existing limits.
