Mesons thiab Baryons Mesons yog cov kab mob uas tuaj yeem lwj mus rau leptons thiab tsis tawm cov hadrons, uas txhais tau hais tias mesons tsis tau khaws cia hauv tus lej.
mesons lwj mus ua dab tsi?
Txhua tus mesons tsis ruaj khov, nrog lub neej nyob ntev tshaj plaws tsuas yog ob peb pua ntawm microsecond. Heavier mesons lwj mus rau meson sib zog thiab thaum kawg rau khov kho electrons, neutrinos thiab photons. … Mesons yog ib feem ntawm tsev neeg hadron particle, uas txhais tau yooj yim raws li cov khoom uas muaj ob lossis ntau dua quarks.
Yuav ua li cas lepton lwj tuaj yeem ua tau?
Tus tau yog tib lub lepton uas tuaj yeem lwj mus rau hauv hadrons - lwm cov lepton tsis muaj qhov tsim nyog. Ib yam li lwm hom kev lwj ntawm cov tau, qhov kev puas tsuaj los ntawm kev tsis muaj zog.
YPob mesons lwj mus ua protons?
Mesons yog hadrons uas tsis lwj mus rau hauv protons, xws li: pions thiab kaons. Pions thiab kaons tuaj yeem yog qhov zoo, nruab nrab thiab tsis zoo. Baryons thiab mesons tsis yog cov khoom tseem ceeb thiab yog li tuaj yeem faib ua cov khoom me me hu ua quarks. Lepton - Lepton yog cov khoom uas cuam tshuam nrog lub zog tsis muaj zog nuclear.
Dab tsi yog qhov sib txawv ntawm lepton thiab mesons?
Lo lus teb yooj yim yog tias baryons yog cov khoom uas muaj peb lub quarks, whereas leptons tsis muaj quarks txhua. Baryons (piv txwv li protons, neutrons) yog ib qho sub-chav kawm ntawm hadrons: hadron yog los ntawm Greek,txhais tau tias hnyav lossis loj. Lepton (xws li electrons) yog lub npe rau lo lus Greek lub ntsiab lus hnyav.
