Tinthu tatsopano tating'onoting'ono tapezeka chifukwa cha akatswiri a sayansi ya zaku Canada

Pa November 19, 2014 Large Hadron Collider Beauty Experiment (LHCb) yochitidwa ndi CERN inapeza tinthu tating'ono tating'ono tating'onoting'ono. Tinthu tating'onoting'ono tidanenedweratu ndi wasayansi waku York University Randy Lewis, ndi Richard Woloshyn wa TRIUMF, labu ya particle physics ku Vancouver. Steven Blusk waku Syracuse University, New York adauza CBC, "Tinali ndi zifukwa zomveka zokhulupirira kuti tinthu tating'onoting'ono tidzakhalapo".

Zomwe zangopezeka kumene, zotchedwa Xi_b'- ndi Xi_b*- , ndi mitundu yatsopano ya baryons. Baryons ndi tinthu tating'onoting'ono tomwe timapangidwa ndi tinthu tating'ono tating'ono tomwe timatchedwa quarks. Tinthu tating'onoting'ono timeneti timafanana ndi ma protoni ndi ma neutroni, omwe amapanga phata la atomu. Tinthu tatsopano tating'onoting'ono timakhala tokulirapo kuwirikiza ka 6 kuposa pulotoni. Izi zilinso ndi b quark, yomwe imakhala yolemera kuposa yomwe imapezeka mu proton, zomwe zimayambitsa kukula kwake. Ma quark ena awiri omwe ali m'malo atsopanowa ndi d quark imodzi; omwe amapezeka mu ma neutroni ndi ma protoni, ndi quark imodzi yapakati yomwe idadziwikabe.

Lewis ndi Woloshyn ananeneratu za kuchuluka ndi kapangidwe ka tinthu tatsopano tating'onoting'ono pogwiritsa ntchito mawerengedwe apakompyuta potengera chiphunzitso cha quantum chromodynamics. Chiphunzitsochi chimafotokoza za tinthu tating'onoting'ono ta zinthu, momwe tinthu tating'onoting'ono timalumikizirana, ndi mphamvu zomwe zili pakati pawo. Kuwerengera komwe kunagwiritsidwa ntchito kumafotokoza malamulo a masamu a momwe ma quarks amachitira.
