“lepton”的概念、定义、习题解题方法及翻译-物理辞典

单词	lepton
释义	lepton Any of a class of elementary particles that consists of the electron, muon, tau particle, and three types of neutrino (one associated with each of the other types of lepton). For each lepton there is an equivalent antiparticle. The antileptons have a charge opposite that of the leptons; the antineutrinos, like the neutrinos, have no charge. The electron, muon, and tau particle all have a charge of -1. These three particles differ from each other only in mass: the muon is 200 times more massive than the electron and the tau particle is 3500 times more massive than the electron. Leptons interact by the electromagnetic interaction and the weak interaction (see fundamental interactions)
