The Mu2e experiment will measure the charged-lepton flavor violating
(CLFV) neutrino-less conversion of a negative muon into an electron in
the field of a nucleus. Mu2e will improve the previous measurement by
four orders of magnitude, reaching a 90% C.L. limit of
8\times10^{-17}8×10−17
on the conversion rate. The experiment will reach mass scales of nearly
10^4104
TeV, far beyond the direct reach of colliders. The experiment is
sensitive to a wide range of new physics, complementing and extending
other CLFV searches. Mu2e is under design and construction at the Muon
Campus of Fermilab; we expect to start taking physics data in 2022 with
3 years of running to achieve our target sensitivity.
