Description

The Mu2e experiment at Fermilab will search for the charged lepton flavor violating (CLFV), neutrinoless conversion of a negative muon into an electron in the field of an aluminum nucleus. This process is forbidden within the Standard Model and remains extremely suppressed in its minimal extensions. The signal would appear as a monoenergetic electron with an energy of 104.97 MeV, just below the muon rest mass. The Mu2e experiment aims to improve the current upper limit on this process by four orders of magnitude, targeting a single event sensitivity (SES) of $3 \times 10^{-17}$. The experiment employs three solenoids arranged in sequence to produce and transport an intense pulsed beam of negative muons. Approximately $10^{18}$ muons are expected to stop in an aluminum target over three years of data taking. The experiment is currently under construction in the experimental hall, and the detector systems are undergoing commissioning. This presentation will outline the physics motivations of Mu2e and describe the design of the experimental apparatus, with particular emphasis on the electromagnetic calorimeter, the main INFN contribution to the experiment. The current status of the experiment and the plans for data taking will also be presented.
