Nyob rau hauv particle physics, mesons (/ˈmiːzɒnz/ los yog /ˈmɛzɒnz/) yog cov subatomic uas muaj cov sib npaug ntawm quarks thiab antiquarks, feem ntau yog ib qho ntawm txhua tus, khi ua ke los ntawm kev sib cuam tshuam zoo. … Heaver mesons lwj mus rau mesons sib zog thiab thaum kawg rau ruaj khov electrons, neutrinos thiab photons.
pi meson txoj kev xav yog dab tsi?
Hideki Yukawa tau txais Nobel nqi zog hauv physics rau xyoo 1949 rau kev kwv yees lub neej ntawm qhov tau los ua lub npe hu ua pi mesons thiab tom qab ntawd ua pions.. quab yuam yog nqa los ntawm ib tug particle nrog ib tug loj kwv yees li 200 npaug ntawm ib tug electron.
Puas yog mesons bosons lossis fermions?
Mesons yog cov khoom nruab nrab nruab nrab uas yog tsim los ntawm ib khub quark-antiquark. Peb quark ua ke yog hu ua baryons. Mesons yog bosons, hos cov baryons yog fermions.
Mesons nyob ua ke li cas?
Nyob hauv mesons thiab baryons, quarks thiab antiquarks tau khi ua ke by gluons, cov nqa ntawm lub zog nuclear. Hauv Tus Qauv Qauv ntawm Particle Physics, gluons tuaj yeem cuam tshuam nrog ib leeg.
Yuav ua li cas baryon muaj 2 nqes quarks?
Txhua baryon muaj cov tshuaj tiv thaiv sib raug hu ua antibaryon uas quarks tau hloov los ntawm lawv cov khoom qub qub. Piv txwv li, ib tug proton yog ua los ntawm ob lub quarks thiab ib tug down quark, thaum nws coj antiparticle, lubantiproton, yog ua los ntawm ob lub antiquarks thiab ib qho antiquark.
