Qhov sib txawv tseem ceeb ntawm muons thiab mesons yog tias muons yog ib hom ntawm cov khoom me me uas tsis muaj kev sib txuas thaum mesons yog ib hom hasronic subatomic particles uas muaj ib khub ntawm quark thiab anti-quark particle.
Muons thiab mesons yog ob hom hais hauv teeb meem. Muons yog ib hom ntawm cov khoom me me xws li hluav taws xob, thiab peb tsis tuaj yeem faib lawv ntxiv rau hauv cov qauv me me (xws li quarks). Tab sis mesons yog me ntsis loj dua muons thiab muaj quark thiab antiquark hais; Yog li, lawv poob rau hauv ib pawg sib txawv hu ua hadronic subatomic hais. Lub sij hawm hadronic txhais tau hais tias nws muaj ob los yog ntau tshaj quark hais, thiab subatomic hais yog cov qauv me dua toms, uas tsim cov qauv ntawm ib lub atom.
Muons yog dab tsi?
Muons yog cov ntsiab lus tseem ceeb uas tsis muaj kev sib txuas. Qhov ntawd txhais tau tias; cov khoom no me me heev, thiab tsis muaj quark lossis antiquark hais hauv lawv. Cov khoom no zoo ib yam li electrons. Lawv muaj -1 tus nqi hluav taws xob thiab lub kiv yog ½. Txawm li cas los xij, lawv muaj qhov loj dua piv rau cov hluav taws xob (txog 207 npaug ntau dua). Tsis tas li ntawd, peb tuaj yeem faib nws li lepton vim nws muaj ib nrab-tus lej sib tw uas tsis muaj kev cuam tshuam zoo. Txawm li cas los xij, cov khoom no yeej tsis cuam tshuam nrog nuclei lossis lwm yam khoom los ntawm kev sib cuam tshuam.

Muons muaj ob daim ntawv raws li cov khoom tsis zoo thiab cov khoom siv hluav taws xob zoo. Lub antiparticle muaj ib tug sib npaug spin thiab loj, tab sis ib tug opposite nqi. Tsis tas li ntawd, cov khoom no tsis ruaj khov, thiab lub neej ntev li ntawm 2.2 s. Txawm li cas los xij, nws yog lub neej ntev dua piv rau lwm cov subatomic hais.
Mesons yog dab tsi?
Mesons yog cov khoom siv subatomic uas muaj ib khub ntawm quark thiab antiquark hais. Ob qhov khoom no khi nrog ib leeg los ntawm kev sib cuam tshuam zoo. Cov no yog lub cev me me me me me vim tias muaj ib khub ntawm substructures (quarks). Nws loj yog 1.2 npaug ntawm proton.
Daim duab 02: Kev faib tawm ntawm cov khoom sib txawv
Txhua mesons yog cov tsis ruaj khov. Lawv lub neej luv heev, txog li ob peb puas ntawm ib microsecond. Tsis tas li ntawd, them meson particle undergoes lwj, tsim electrons thiab neutrinos. Uncharged mesons, ntawm qhov tod tes, lwj-tsim photons. Kev npam ntawm meson yog 1.
Qhov txawv ntawm Muons thiab Mesons yog dab tsi?
Muons yog cov ntsiab lus tseem ceeb uas tsis muaj kev cuam tshuam thaum mesons yog cov khoom siv subatomic uas muaj ib khub ntawm quark thiab antiquark hais. Yog li, qhov sib txawv tseem ceeb ntawm muons thiab mesons yog tias cov muons yog ib hom ntawm cov khoom me me uas tsis muaj kev sib txuas, hos cov mesons yog ib hom ntawm cov kab mob subatomic uas muaj ib khub ntawm quark thiab anti-quark particle.
Ntxiv mus, qhov sib txawv ntxiv ntawm muons thiab mesons yog qhov loj ntawm muon me me, zoo ib yam li electron, thaum meson loj thiab nws yog li 1.2 npaug ntawm qhov loj ntawm proton. Tsis tas li ntawd, lub muon muaj ib tug ½ integer spin, tab sis lub spin ntawm ib tug meson yog 0 los yog 1.
Summary – Muons vs Mesons
Muons yog cov ntsiab lus tseem ceeb uas tsis muaj kev cuam tshuam thaum mesons yog cov khoom siv subatomic uas muaj ib khub ntawm quark thiab antiquark hais. Qhov sib txawv tseem ceeb ntawm muons thiab mesons yog tias cov muons yog ib hom ntawm cov khoom me me uas tsis muaj kev sib txuas, hos cov mesons yog ib hom ntawm cov kab mob subatomic uas muaj ib khub ntawm quark thiab anti-quark particle.
