Ma hadrons achilendo, kapena physics, akupitiriza kudabwitsa

Asayansi a CERN amatsimikizira kuti kuyesa ku Large Hadron Collider, yotchedwa Large Hadron Beauty Collider (LHCb), yapeza tinthu tatsopano totchedwa "exotic hadrons". Dzina lawo limachokera ku mfundo yakuti sangatengedwe kuchokera ku chikhalidwe cha quark.

Ma hadroni ndi tinthu tating'onoting'ono tomwe timalumikizana mwamphamvu, monga momwe timalumikizirana mkati mwa nucleus ya atomiki. Malinga ndi malingaliro a zaka za m'ma 60, amakhala ndi quarks ndi antiquarks - mesons, kapena atatu quarks - baryons. Komabe, tinthu tating'onoting'ono ta LHCb, tolembedwa kuti Z (4430), sikugwirizana ndi chiphunzitso cha quark, chifukwa chitha kukhala ndi ma quarks anayi.

Zoyamba za tinthu zachilendo zidapezeka mu 2008. Komabe, zakhala zotheka posachedwa kutsimikizira kuti Z(4430) ndi tinthu tating'onoting'ono tokhala ndi 4430 MeV/c², yomwe ili pafupifupi kuwirikiza kanayi kuchuluka kwa proton (938 MeV/c²). Asayansi sananenebe tanthauzo la kukhalapo kwa ma hadron achilendo.
