13:00 → 14:00 Searching for CLFV at Mu2e

Charged Lepton Flavor Violating (CLFV) processes constitute unambiguous evidence for new physics, with multiple models predicting signals accessible by current experiments. The Mu2e experiment at Fermilab will search for evidence of CLFV in the neutrinoless conversion of a muon to an electron in the field of a nucleus. This process results in a monoenergetic conversion electron with an energy of 104.97 MeV, just below the muon rest mass. Mu2e aims to improve on the previous SINDRUM-II limit on muon to electron conversion by four orders of magnitude, achieving a single-event sensitivity of 3E-17 on the conversion rate relative to muon capture. To accomplish this, Mu2e relies on an intense, pulsed muon beam delivered by the Fermilab accelerator complex and the Mu2e magnet system, as well as detectors designed to reconstruct signal electrons with narrow momentum resolution while filtering out background. In this talk, I will discuss the current status of Mu2e and progress towards the initial Run I data-taking period at the end of 2027. I will also discuss my own work towards improving the electron momentum resolution by precisely mapping the Mu2e magnetic field in the detector volume.
