Lepton Flavour Violation

Lepton Flavour Violation (LFV) refers to processes where a lepton (a type of fundamental particle like electrons, muons, or tau particles) transforms into another lepton of a different type, which is not allowed in the Standard Model of particle physics without involving neutrinos. For example, a muon decaying into an electron and a photon would be an LFV process. Detecting LFV would indicate new physics beyond current theories, providing insight into the fundamental laws governing particles and possibly explaining phenomena like neutrino masses.
