Ib txhia bosons kuj muaj antiparticles, tab sis vim bosons tsis ua raws li Pauli cais txoj cai (tsuas yog fermions ua), qhov kev xav tsis ua hauj lwm rau lawv.
W bosons puas muaj tshuaj tiv thaiv?
Muaj ob hom khoom hauv tus qauv qauv: fermions, qhov teeb meem, thiab bosons, cov cab kuj. Tsuas yog fermions, uas tau muab faib ua quarks thiab lepton, muaj cov khoom tiv thaiv, hais tias Taylor. … Tsis yog hais tias W+ thiab W- bosons yog ib qho kev tawm tsam ntawm ib leeg, nws hais.
Yuav ua li cas cov particles muaj antiparticles?
Feem ntau cov hauv paus ntsiab lus muaj cov khoom sib txuam sib luag, nrog tib lub zog, lub neej, thiab kiv, tab sis nrog cov cim qhia ntawm tus nqi (hluav taws xob, baryonic, lossis leptonic). Lub electron-positron, proton-antiproton, thiab neutron-antineutron yog cov piv txwv ntawm cov khub no.
Puas yog txhua qhov particle puas muaj cov tshuaj tiv thaiv?
Raws li quantum teb txoj kev xav txhua qhov kev them nqi muaj nws cov tshuaj tiv thaiv, cov particle nrog tib qhov loj thiab kiv tab sis tus nqi sib txawv. Qhov kev tshwm sim dav dav ntawm quantum field theory tau lees paub los ntawm tag nrho cov ntaub ntawv kev sim uas twb muaj lawm. Lub antiparticle ntawm lub electron yog lub positron.
Puas bosons muaj 0 kiv?
Bosons yog cov particles uas muaj integer spin (0, 1, 2…). Tag nrho cov khoom siv quab yuam yog bosons, ib yam li cov khoom sib xyaw nrog ib tus lej ntawm fermion hais (xws li mesons).
