Lepton Taw Qhia
Tus lepton yog qhov fermion nrog tus kiv ћ / 2 uas tsis koom nrog kev sib tham muaj zog. Lepton suav nrog cov khoom siv hluav taws xob, muons, τ particles thiab lawv cov neutrinos sib xws (,e, νμ, thiab ant thiab lawv cov tshuaj tiv thaiv). Cov e-, μ-, thiab τ-hais muaj qhov ntau ntawm 0.51 mega-hluav taws xob volts, 105.66 mega-hluav taws xob volts, thiab 1,776.99 mega-electron volts, feem, thiab lawv txhua tus nqa ib qho tsis zoo rau kev them nqi. Lawv antiparticles e +, μ +, thiab τ + nqa ib chav ntawm kev them nqi zoo. Neutrinos thiab lawv cov tshuaj tiv thaiv kab mob tsis raug them thiab yog cov nruab nrab nruab nrab. Cov kev sim hauv lub xyoo tam sim no tau qhia tias neutrinos muaj qhov tsis-xoom zoo li qub.
