Lepton Flavor Violation

Lepton flavor violation (LFV) refers to the process where a lepton (like an electron, muon, or tau) changes into another type of lepton, which is not allowed by the Standard Model of particle physics under normal circumstances. For example, a muon transforming into an electron without pairing with a neutrino is an LFV event. Observing LFV would indicate new physics beyond current theories, providing insights into fundamental forces and particles. Although LFV processes are extremely rare or unmeasured so far, studying them helps scientists explore potential extensions to our understanding of the universe.
