Ib txwm mesons yog tsim los ntawm valence quark thiab valence antiquark. Vim hais tias mesons muaj spin ntawm 0 los yog 1 thiab tsis yog lawv tus kheej cov ntsiab lus, lawv yog "composite" bosons.
Dab tsi yog mesons?
Meson, ib qho tus tswvcuab ntawm tsev neeg ntawm subatomic hais muaj li ntawm quark thiab antiquark. Mesons yog rhiab heev rau lub zog muaj zog, lub hauv paus kev sib cuam tshuam uas khi cov khoom ntawm lub nucleus los ntawm kev tswj hwm tus cwj pwm ntawm lawv cov quarks.
Qhov twg tsis yog lub ntsiab lus tseem ceeb?
X-rays tsis yog cov khoom, lawv yog electromagnetic nthwv dej uas muaj zog dua UV thiab tsawg zog dua gamma rays. Yog li, lawv tsis yog cov khoom tseem ceeb.
Dab tsi yog cov ntsiab lus tseem ceeb hauv cov nucleus?
Atom Builder Guide to Elementary Particles
Atoms yog tsim los ntawm ob hom elementary hais: electrons thiab quarks. Cov hluav taws xob nyob ib puag ncig ib puag ncig lub atom lub nucleus. Txhua tus electron muaj cov nqi hluav taws xob ntawm -1. Quarks tsim cov protons thiab neutrons, uas, nyob rau hauv lem, ua ib tug atom lub nucleus.
Dab tsi yog qhov tsawg tshaj plaws lub hauv paus particle?
Quarks yog cov khoom me tshaj plaws uas peb tau hla hauv peb txoj kev sim siab. Qhov Discovery ntawm quarks txhais tau hais tias protons thiab neutrons tsis yog qhov tseem ceeb ntxiv lawm.
