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).

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Cov tshuaj tiv thaiv puas tiv thaiv kab mob?
Cov ntaub ntawv tshiab kawg qhia tau tias kev txhaj tshuaj tsis yog tiv thaiv tib neeg cov tshuaj tiv thaiv xwb, nws txo qis txoj hauv kev uas lawv tuaj yeem kis tus kabmob mus rau lwm tus. Cov tshuaj tiv thaiv COVID-19 puas tiv thaiv kev sib kis?

Cov tshuaj tiv thaiv Delta muaj txiaj ntsig zoo li cas ntawm cov tshuaj tiv thaiv COVID-19? Hais txog Delta Variant: Cov tshuaj tiv thaiv muaj txiaj ntsig zoo rau kev mob hnyav, tab sis Delta variant ua rau ntau dua Kev kis kab mob thiab kis tau sai dua li cov qauv ua ntej ntawm tus kab mob uas ua rau COVID-19.
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
Cov tshuaj tiv thaiv kab mob puas muaj kev tiv thaiv kab mob?
Nws yuav siv sijhawm ntev npaum li cas txhawm rau txhim kho kev tiv thaiv kab mob COVID-19 tom qab tau txais cov tshuaj tiv thaiv? tshuaj tiv thaiv COVID-19 qhia peb lub cev tiv thaiv kab mob kom paub txog thiab tawm tsam tus kab mob uas ua rau COVID-19.
