Abstract, Event Details: 

Muons, heavy cousins of electrons whose existence famously puzzled I.I. Rabi, may play an important role in understanding the behavior of particles and fields at the highest energies. Searches for transitions that violate the apparent lepton flavor conservation are sensitive to new interactions with the energy scale above those accessible in the modern colliders. Recent hints of deviations from the Standard Model expectations in the processes involving muons are intriguing, and motivate new measurements over the next decade. Among those, the Mu2e experiment at Fermilab will search for neutrinoless muon-to-electron conversion with unprecedented precision. I will discuss the history of the lepton flavor measurements, and describe the design and present status of Mu2e, which will improve the current constraints by four orders of magnitude.
