Xyoo 1935, Hideki Yukawa tau hais tias lub zog electromagnetic tsis muaj qhov kawg vim cov khoom sib pauv tsis muaj huab hwm coj. Nws tau hais tias qhov luv luv muaj zog quab yuam los ntawm kev sib pauv ntawm cov khoom loj uas nws hu ua meson. … Qhov kwv yees particle loj yog kwv yees li 100 MeV.
Dab tsi yog cov khoom sib pauv?
Gluons yog cov khoom sib pauv rau cov xim quab yuam ntawm quarks, zoo ib yam rau kev sib pauv ntawm photons hauv electromagnetic quab yuam ntawm ob qhov hluav taws xob. … Lub gluon tuaj yeem suav hais tias yog qhov kev sib pauv pauv tseem ceeb hauv qab ntawm kev sib cuam tshuam ntawm protons thiab neutrons hauv lub nucleus.
Yog mesons baryons?
Baryons thiab mesons yog piv txwv ntawm hadrons. Txhua qhov hais tias muaj quarks thiab paub txog lub zog muaj zog nuclear yog ib qho muaj zog. Baryons muaj peb quarks hauv lawv, thaum mesons muaj quark thiab antiquark.
Puas yog mesons elementary particles?
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.
Yuav ua li cas paub lub zog tshaj plaws hauv lub qab ntuj khwb?
Lub zog muaj zog nuclear, tseem hu ua kev sib cuam tshuam nuclear muaj zog, yog qhov muaj zog tshaj plaws ntawm plaub lub zog ntawm qhov xwm txheej. Nws yog 6 txhiab trillion trillion trillion(uas yog 39 xoom tom qab 6!) lub sij hawm muaj zog tshaj qhov quab yuam ntawm lub ntiajteb txawj nqus, raws li HyperPhysics lub vev xaib.
