The other leptons are electrons,taus,and three kinds of neutrinos, which are electrically neutral leptons which are massless or nearly massless. A muon has a greater mass than an electron, about 207 times heavier. However, muons are like electrons because they both have negative charges.
Muons are unstable particles.
Muons are produced in particle physics experiments. Because they are much more massive than electrons, muons readily pass through the electric fields inside matter with very little deflection. So, muons do not radiate and slow down as electrons do. However, they can cause ionization and this makes them readily detectable in matter, for example, with a Geiger counter. Muons can travel large distances through matter with very little interacting, compared to other charged particles, such as an electron.
