'''Lepton''' adalah sebuah kelompok [[partikel dasar]], bersama-sama dengan [[kuark]] dan [[gauge boson]].
Seperti kuark, lepton merupakan [[fermion]] (partikel spin {{frac|1|2}}) dan dipengaruhi oleh [[gaya elektromagnetik]], [[gaya gravitasi]], dan [[gaya lemah]], namun berbeda dengan kuark, lepton tidak ikut serta dalam [[interaksi kuat]].
Baris 7 ⟶ 31:
Ada enam [[rasa (fisika)|rasa]] lepton, yang membentuk tiga generasi. Generasi pertama adalah ''lepton elektronik'', yang terdiri dari [[elektron]] dan [[neutrino elektron]]. Generasi kedua adalah [[lepton muon]], terdiri dari [[muon]] dan [[neutrino muon]], sedangkan generasi ketiga adalah [[tau lepton|tauon]] dan [[neutrino tauon]]. Tiap lepton memiliki antipartikel, yang dikenal sebagai ''antilepton''.
Lepton adalah bagian penting dari [[Model standar]],
