Lepton flavor violation is a phenomenon in particle physics where the flavor of a lepton (such as an electron, muon, or tau) changes during a particle interaction. This violation of lepton flavor conservation is not predicted by the Standard Model of particle physics and can provide valuable insights into physics beyond the Standard Model. Research in lepton flavor violation focuses on studying rare processes where these flavor-changing interactions occur, and searching for new particles or interactions that could explain these phenomena. Studying lepton flavor violation can help scientists better understand the fundamental properties of particles and the nature of the universe.
