Kuwanikwa kweiyo Xi-cc-plus particle paLHC inosimbisa quantum modhi

Iyo Grande Colisor ye Hadrons (LHC), inoshandiswa neEuropean laboratory Cern, yaona imwe subatomic particle itsva inonzi Xi-cc-plus. Kuonekwa kwakaitika kuburikidza nekuedza kweLHCb, iyo yakaongorora kudhumhana kweproton yakakura. Essa chidimbu chinomiririra kuwanikwa kwemakumi masere kwerudzi rwayo mune inomhanyisa simba pasi rose uye yakaziviswa munaKurume 17, 2026, pamusangano wesainzi unoenderera mberi. Xi-cc-plus ine charm quarks mbiri uye imwe pasi quark, iyo inoita kuti ireme zvakapetwa kana kupfuura yenguva dzose proton. Cientistas inosimbisa kuti kutarisa kunobatsira kunzwisisa zviri nani kupindirana kwakasimba kunobatanidza quarks muzvikamu zvakaumbwa.

Icho chidimbu chakagadzirwa mukudhumhana kwakanyorwa neLHCb detector, yakagadziridzwa muna 2023 kuti iwedzere kuyerwa chaiko. Essa kunatsiridza kwakaita kuti zvikwanise kuziva Xi-cc-plus sechinhu chitsva chekutanga chakaonekwa mushure mekugadzirisa michina. Chimiro chechikamu chinosanganisira maviri anorema charm quarks, achitsiva kumusoro quarks aripo muproton. Essa isingawanzo gadziriso inoita kuti Xi-cc-pamwe muenzaniso unokosha webhayoni yakapetwa kaviri.

Yakawanikwa chidimbu chimiro

Xi-cc-plus is baryon, chikamu chezvikamu zvakaumbwa netatu quarks. Seus zvikamu zviviri zvecharm quarks uye imwe pasi quark. Yakajairwa Prótons ine maviri kumusoro uye imwe pasi quarks, izvo zvinotsanangura musiyano wakakosha muhuwandu. Iyo nyowani nyowani inoratidza zvivakwa zvinopokana nefungidziro chaiyo kubva kune etioretical modhi asi ichienderana nequantum chromodynamics.

Masayendisiti akaona kuti Xi-cc-plus ine hupenyu hupfupi kwazvo, pahurongwa hwezvikamu zvesekondi. Apesar Uyezve, kuonekwa kwayo kunopa ruzivo rwemaitiro eheavy quarks. Kuwanikwa uku kunosimbisa kufanotaura kwakaitwa makumi emakore apfuura kune mabhayoni ane maviri anorema quark.

Mamiriro ekuedza kweLHCb

LHCb inotarisa pakudzidza zvidimbu zvine pasi uye charm quarks. Iyo detector inotora zvakaora zvakaora zvinoitika pamakona akasiyana pane mamwe maLHC kuyedza. Essa chimiro chakaibvumira kupatsanura masiginecha kubva kuXi-cc-plus pakati pemabhiriyoni ekudhumhana. Kubatana uku kunosanganisira vanopfuura chiuru vaongorori vanobva kunyika dzakasiyana.

Kukwidziridzwa kwakapedzwa muna 2023 kwaisanganisira masensa matsva uye masisitimu ekuverenga nekukurumidza. Essas shanduko dzakawedzera kugona kurekodha zviitiko zvisingawanzo. Kuonekwa kweXi-cc-plus kunoratidza kushanda kwekuvandudzwa kwakaitwa.

Kuenzanisa nezvakawanikwa kare

Muna 2017, LHCb yakaratidza chidimbu chakafanana, Xi-cc-plus ine kumusoro quark panzvimbo yekudzika. Aquela kutarisa kwakaratidza kuonekwa kwekutanga kwebaryon ine charm quarks mbiri. Iyo nyowani nyowani inopedzisa iyo yakafanotaurwa peya, ichibvumira kuenzanisa kwakananga pakati pezvigadziriso. Ambas zvidimbu zvinobatsira kusimbisa dzidziso pamusoro pesimba rakasimba pazvikero zvesubatomic.

Musiyano mukuwanda uye kuora pakati pezvimedu zviviri zvinopa bvunzo dzakasimba dzemhando. Kuvapo kwecharm quarks kunoshandura bond dynamics, iyo inokanganisa zvivakwa zvakadai sekugadzikana uye kupindirana.

Kukosha kwe quantum chromodynamics

Dzidziso ye quantum chromodynamics inotsanangura kuti quarks inobatanidzwa sei kuburikidza nesimba rakasimba. Kuwanikwa kweXi-cc-plus kunopa rabhoritari itsva yekuyedza maverengero chaiwo edzidziso iyi. Modelos inofanotaura kuti mauto anosunga anokura nechinhambwe chiri pakati pe quarks, zvakafanana nechitubu.

Zvimedu zvakaita se Xi-cc-plus zvinoita kuti zvikwanise kuyera kusangana uku pasi pemamiriro akanyanya. Resultados inobatsira kunatsa fungidziro pamusoro pemaharons ekunze, kusanganisira tetraquarks uye pentaquarks. Iyo LHC inoramba ichigadzira data kuti iongorore izvi zviitiko.

Accelerator Maonero

Iyo LHC inoshanda nekudhumhana kweproton pa13.6 TeV. Mhete yemakiromita makumi maviri nemanomwe inomhanyisa twunhu kusvika pakumhanya pedyo nekwechiedza. Experimentos seLHCb inoongorora matiririyoni ezviitiko kuona kuora kusingawanzo. Kuwanikwa kwacho kunosimbisa basa reiyo accelerator muchikamu chefizikisi.

Masayendisiti anoronga kumwe kuongorora kwe data yakaunganidzwa. Novas zvakaonekwa zvinogona kusimbisa zvimiro zveXi-cc-plus uye kutsvaga zvidimbu zvinoenderana. Iyo LHC inoramba iri chishandiso chikuru chekufambira mberi munzvimbo iyi.

Detection technical details

Chidimbu chinobuda mukudhumhana kwesimba guru uye chinokurumidza kuora kuva zvimwe zvimedu. Rastros yasara mumudziyo inotitendera kuti tigadzirise kuvepo kwayo. Análises nhamba dzinosimbisa chiratidzo chine kukosha kwepamusoro. Kubatana kweLHCb kwakaburitsa zvakabuda pamusangano uchangopfuura.

Huremu hwe Xi-cc-plus hunodarika nemapurotoni, nekuda kwekuremerwa kwecharm quarks. Essa chimiro chinofambisa zvidzidzo zvekuenzanisa nemabhayoni akareruka.

Kufambira mberi mushure mekusimudzira detector

Kukwidziridzwa kwa2023 kwakawedzera LHCb yenguva uye gadziriso yenzvimbo. Zvimwe zvemberi Sensores tora zviitiko nemazvo. Essa huwandu hwaive hwakakosha kupatsanura Xi-cc-plus kubva kune ruzha rwekumashure. Kuwanikwa kunosimbisa mari mukuvandudza tekinoroji.

Vatsvaguri vanoramba vachigadzira data kubva kuRun 3. Novas zvidimbu zvinogona kubuda mune ramangwana ongororo. LHCb inotarisa pane inorema quarks kuburitsa zvakavanzika zvenyaya.

Kuwanikwa kweXi-cc-plus kunopfumisa iyo catalog yeanozivikanwa hadrons. Ela inopa data rakaoma kune zvakakosha dzidziso. Cern inoenderera mberi nekushandisa accelerator kuti ienderere mberi.
