The Mu2e experiment at Fermi National Accelerator Laboratory will investigate Charged Lepton Flavour Violation by searching for coherent muon to electron conversion in the coulomb field of an Al nucleus. Although allowed due to neutrino oscillations, this conversion is suppressed by the Standard Model with an expected BR < 10^-54. Therefore, the observation of this process would be a clear evidence of New Physics beyond the SM. Over three years of run time, over 6x10^17 muons will be stopped on the Mu2e target, allowing a single event sensitivity of approximately 2.5×10^-17, probing 4 orders of magnitude beyond the current best experimental limit of 7×10^&#8722;13 @ 90% CL set by SINDRUM II.
