Lub gluon tau tshawb pom ntawm lub electron-positron collider PETRA ntawm DESY, lub teb chaws Yelemees, nyob rau lub caij nplooj ntoos hlav lig xyoo 1979. Nws yog qhov ntsuas thib ob uas tau tshawb pom hauv kev sim, lub thawj tus yog photon ntau tshaj 50 xyoo dhau los.
gluons tuaj qhov twg?
40 xyoo dhau los, xyoo 1979, kev sim ntawm DESY lub chaw kuaj mob hauv lub tebchaws Yelemes muab thawj cov pov thawj ncaj qha ntawm lub neej ntawm gluons - cov nqa ntawm lub zog uas "kua nplaum" quarks rau hauv cov protons, neutrons thiab lwm yam khoom uas paub ua ke raws li hadrons.
Peb paub li cas gluons muaj nyob?
Gluons tau ntes tau los ntawm cov dav hlau ntawm cov khoom siv roj av uas lawv tsim nyob rau hauv lub ntsuas particle sai tom qab lawv tau tsim thawj zaug. … Qee lub sij hawm ib qho ntawm lub xeev kawg quarks radiates ib gluon ua ntej nws "hadronizes" (uas yog, cov ntaub ntawv rau hauv hadrons xws li protons, pions, neutrons, thiab lwm yam).
quarks thiab gluons nyob qhov twg?
Txhua yam uas pom tau pom feem ntau yog tsim los ntawm quarks, down quarks thiab electrons. Vim muaj qhov tshwm sim hu ua xim kaw, quarks yeej tsis pom nyob rau hauv kev sib cais; Lawv tuaj yeem pom tsuas yognyob rau hauv hadrons, uas suav nrog baryons (xws li protons thiab neutrons) thiab mesons, lossis hauv quark–gluon plasmas.
Leej twg pom gluons?
Nyob rau xyoo 1976, Mary Gaillard, Graham Ross thiab tus kws sau ntawv tau tawm tswv yim nrhiav gluon ntawm 3-jet xwm txheej vim gluon bremsstrahlung hauv e^+ e^- kev sib tsoo. Ua raws li peb cov lus qhia, lub gluon tau tshawb pom ntawm DESY xyoo 1979 los ntawm TASSO thiab lwm yam kev sim ntawm PETRA collider.
