Muon-to-electron conversion violates the lepton family number, changing a muon to an electron in the field of a nucleus through a coherent interaction with the nucleus. Since no neutrinos are produced, muon-to-electron conversion is not a weak interaction: thus an observation of the process can only come from new physics. Thus, one of the many probes
for Beyond Standard Model (BSM) studies is the search for Charged Lepton Flavor Violation (CLFV). The Mu2e experiment at Fermilab will search for the neutrinoless muon-to-electron conversion in the nuclear field. In the case of an Aluminum target, the experimental signature of this process is a 104.97 MeV mono-energetic electron conversion.  We plan to measure the ratio of muon-to-electron conversion with respect to all muon captures with a precision of 3 X 10^-17. This would be an improvement of four orders of magnitude over the current best limit of 7 x 10^-13 (90% CL) by the SINDRUM-II experiment. 

In this seminar, I will begin with various CLFV experiments across the world with a prime focus on one of the golden channel experiments: μ N → e N. Then, I will explain the Physics goals, unique design, and detector components of Mu2e. Further, the installation of components, recent R&D work, and a plan for a possible successor Mu2e-II will also be highlighted.
