Thaum ib qho hluav taws xob thiab positron (antielectron) sib tsoo ntawm lub zog siab, lawv tuaj yeem rhuav tshem los tsim cov quarks ntxim nyiam uas tom qab ntawd tsim D+ thiab D - mesons.
Yuav ua li cas thaum photons sib tsoo?
Yog tias ob lub taub hau photons rau ib leeg thiab lawv ob leeg tig mus ua electron / anti-electron khub ntawm tib lub sijhawm, ces cov khoom no tuaj yeem cuam tshuam. Lub anti-electron los ntawm ib tug photon yuav tsoo nrog ib tug electron los ntawm lwm yam photon, thiab tig rov qab mus rau lub teeb.
Dab tsi yog tsim thaum lub positron thiab ib qho hluav taws xob sib tsoo quizlet?
Thaum ib qho hluav taws xob thiab positron sib tsoo kom rhuav tshem thiab tsim gamma rays, lub zog raug muab tawm. … Qhov no yog vim li cas ob lub gamma rays raug tsim.
Puas yog positron thiab electron sib tsoo?
Nyob hauv particle physics, annihilation yog cov txheej txheem uas tshwm sim thaum lub subatomic particle collides nrog nws cov antiparticle los tsim lwm yam, xws li ib tug electron tsoo nrog ib tug positron los tsim ob. photons.
Thaum twg positron thiab ib qho hluav taws xob sib tsoo hauv lub hnub lawv tsim?
Lub positron nws thiaj li sib tsoo nrog ib qho hluav taws xob (txhua tus yog qhov sib npaug ntawm lwm tus) thiab lawv ob leeg tig mus rau gamma rays. Lub neutrino tawm lub Hnub ntawm ze li lub teeb nrawm, siv ob peb feeb xwb.
