Thawj zaug tau pom ntawm LHC, χb(3P), tau tshawb pom los ntawm ATLAS, thiab cov tsis ntev los no suav nrog kev zoo siab tshiab zoo nkauj coj txawv txawv baryon pom los ntawm CMS thiab plaub tetraquarks kuaj pom los ntawm LHCb.
Hardrons pom nyob qhov twg?
Txhua qhov pom ntawm subatomic hais yog hadrons tshwj tsis yog rau qhov ntsuas bosons ntawm kev sib cuam tshuam thiab cov leptons. Tsuas yog cov protons thiab neutrons uas khi rau hauv atomic nuclei, tag nrho cov hadrons muaj lub neej luv thiab yog tsim nyob rau hauv lub zog siab sib tsoo ntawm subatomic particles.
Thaum twg yog thawj quark nrhiav pom?
Tus qauv quark tau tawm tswv yim ntawm tus kheej los ntawm tus kws kho mob Murray Gell-Mann thiab George Zweig hauv xyoo 1964. Quarks tau qhia los ua ib feem ntawm cov txheej txheem xaj rau hadrons, thiab tsis muaj pov thawj me me rau lawv lub cev muaj sia mus txog qhov sib sib zog nqus inelastic scattering thwmsim ntawm Stanford Linear Accelerator Center hauv 1968.
Dab tsi subatomic hais nyob rau xyoo 1920?
May 1932: Chadwick Tshaj Tawm Txog Kev Tshawb Fawb ntawm Neutron. Los ntawm 1920, physicists paub tias feem ntau ntawm cov loj ntawm lub atom nyob rau hauv ib tug nucleus ntawm nws qhov chaw, thiab hais tias lub hauv paus tseem ceeb no muaj protons.
Dab tsi tau pom ntawm CERN?
Lub Xya Hli 2012, CERN cov kws tshawb fawb tau tshaj tawm qhov kev tshawb pom ntawm ib qho tshiab sub-atomic particle uas tom qab tau lees paub tias yog the Higgs boson. Thaum Lub Peb Hlis 2013, CERN tau tshaj tawm tias qhov ntsuas tau ua rauqhov pom tshiab tau tso cai rau nws xaus tias qhov no yog Higgs boson.
