Antiparticle, subatomic particle muaj tib qhov loj liib qho ntawm cov khoom ntawm cov teeb meem zoo tib yam tab sis rov qab hluav taws xob thiab lub sijhawm sib nqus.
Dab tsi yog qhov txawv ntawm particle thiab antiparticle?
Matter – Antimatter Annihilation
Raws li tau sau tseg, ib qho particle thiab nws cov antiparticle muaj tib lub zog ib yam, tab sis tawm tsam hluav taws xob, thiab lwm qhov sib txawv hauv tus lej quantum. Qhov ntawd txhais tau hais tias tus proton muaj tus nqi zoo thaum lub antiproton muaj cov nqi tsis zoo thiab yog li lawv sib nyiam.
Vim li cas txhua qhov particle muaj cov tshuaj tiv thaiv?
Raws li quantum teb txoj kev xav txhua qhov kev them nqi muaj nws cov tshuaj tiv thaiv, cov khoom uas muaj tib lub loj thiab tig tab sis rov qab them nqiQhov 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 tau particle thiab antiparticle nyob ua ke?
Particle–antiparticle annihilation, tsis tuaj yeem tshwm sim hauv qhov chaw dawb vim tias nws tsis tuaj yeem khaws lub zog thiab lub zog ua ke hauv cov txheej txheem no.
Dab tsi yog nws tus kheej antiparticle?
Ib tug particle uas yog nws tus kheej antiparticle yog
the photon , ib tug particle ntawm lub teeb. Lwm qhov yog qhov nruab nrab pion, uas yog tsim los ntawm quark-antiquark khub, thiab gluon, uas ua rau quarks ua ke.
