Ib txhia hais, xws li cov photon, yog lawv tus kheej antiparticle … Lwm yam (feem ntau muab cov lus ua ntej "anti-") yog xaiv cov tshuaj tiv thaiv. Particle-antiparticle khub tuaj yeem rhuav tshem ib leeg, tsim cov photons; txij li cov nqi ntawm cov particle thiab antiparticle yog opposite, tag nrho cov nqi yog conserved.
Qhov twg yog nws tus kheej antiparticle?
Ib tug particle uas yog nws tus kheej antiparticle yog
the photon , ib particle ntawm lub teeb.
Vim li cas photon yog antiparticle ntawm nws tus kheej?
Lub neutron yog tsim los ntawm 3 quarks, uas muaj cov nqi hluav taws xob, yog li cov antineutron yog tsim los ntawm 3 antiquarks. Yog cov particle yog qhov tseemceeb, nws yog hais tias nws yog antiparticle ntawm nws tus kheej. Nov yog rooj plaub photon.
Puas yog neutron nws tus kheej antiparticle?
Ib lub neutron tsis tuaj yeem ua nws tus kheej antiparticlevim nws yog tsim los ntawm quarks thiab antineutron yog tsim los ntawm antiquarks. Lub pi_0 yog tsim los ntawm quark thiab antiquark thiab yog qhov tseeb nws tus kheej antiparticle kuj. Koj tuaj yeem pom ntau yam hais txog cov khoom ntawm, ib feem ntawm Particle Data Group's.
Dab tsi yog qhov antiparticle ntawm proton?
Cov positron tau tshawb pom los ntawm C. D. Anderson hauv xyoo 1932. Cov tshuaj tiv thaiv ntawm cov proton yog cov antiproton, cov particle nrog hluav taws xob sib npaug rau −e thiab ib pawg sib npaug ntawm cov proton. pawg. Lub antiproton tau pom nyob rau hauv 1955 los ntawm O.
