Leptons are fundamental particles . They feel neither the color force nor the nuclear force . That means that they can wander about freely in contrary to quarks which are always bound by the color force. It also means that a lepton can fly right through a nucleus without feeling a thing because it is not affected by the nuclear force.

There are six flavors of leptons, arranged in three generations
