lepton flavor

Lepton flavor refers to the different types or categories of leptons, which are elementary particles like electrons, muons, and taus. Each lepton type has unique properties such as mass and decay behaviors, and they do not change from one type to another under normal conditions. In particle physics, lepton flavor conservation means that, in most processes, the number of each lepton type remains the same. However, recent discoveries show that leptons can sometimes change flavors through specific interactions, revealing deeper insights into fundamental forces and particles.
