Euroopa tuumauuringute keskuse CERN-i Suures Tuumaosakeste P\u00f5rgutis Genfi l\u00e4hedal maa-aluses r\u00f5ngastunnelis on v\u00e4ikesi aineosakesi suure hooga p\u00f5rkuma pannud f\u00fc\u00fcsikud m\u00e4rganud v\u00f5imalikke pisikesi k\u00f5rvalekaldeid osakeste standardmudeli teoreetilistest ennustustest, mis v\u00f5ivad osutada, et standardmudel sisaldab vastuolusid ja tuleb asendada millegi muuga.<\/p>\n

Teadlased on nimelt l\u00e4hemalt uurinud, kuidas lagunevad 27 kilomeetri pikkuses tunnelis toimuvail osakestep\u00f5rkeil tekkivad B-mesonid, kvargist ja antikvargist koosnevad osakesed.<\/p>\n

B-mesoni lagunemisel v\u00f5ib tekkida v\u00e4ga mitmesuguseid osakesi, igat komplekti mingi t\u00f5en\u00e4osusega.<\/p>\n

Teadlased on n\u00fc\u00fcd aga t\u00e4hele pannud, et niisugust B-mesoni laguosakeste komplekti, mis koosneb \u00fchest kaaonist, \u00fchest piionist ja kahest m\u00fc\u00fconist, tekib natuke harvem kui standardmudelist peaks tulenema. Seda osakeste komplekti peakski tekkima v\u00e4ga harva, aga katses selgub, et seda tekib mudeli ennustatust harvemgi veel.<\/p>\n

<\/p>\n

Peale selle erinevad standardmudeli p\u00f5hjal prognoositust ka suunad, milles selle komplekti laguosakesed s\u00fcndmuspaigalt pagevad, mis samuti viitab, et midagi v\u00f5ib asjakohaseis f\u00fc\u00fcsikaseadusis olla teisiti kui arvatud.<\/p>\n

Teadlased kirjutavad ajakirjas Physical Review Letters<\/a>, et B-kvargi ehk p\u00f5hjakvargi ja m\u00fc\u00fconi vaheline vastastikm\u00f5ju tundub katse p\u00f5hjal olevat p\u00e4ris palju v\u00e4ikesem kui teooria ette n\u00e4eb \u2014 isegi peaaegu nii palju v\u00e4iksem, aga mitte ka p\u00e4ris nii palju, et standardmudelit saaks ametlikult k\u00f5igutama hakata.<\/p>\n

Tulemus viib teadlasi m\u00f5ttele, et maailmas v\u00f5ib olemas olla mingeid ebatavaliselt suure massiga osakesi, mis aitaksid tuvastatud k\u00f5rvalekallet seletada, aga CERN-is neid osakesi paraku otseselt luua ei saa.<\/p>\n

Teadlased loodavad, et midagi selgemat v\u00f5ib ilmsiks tulla, kui Suurt Tuumaosakeste P\u00f5rgutit tulevikus t\u00e4iustatakse.<\/p>\n

Praegu aga j\u00e4\u00e4b standardmudel p\u00fcsima, sest seni n\u00e4ha olevad ebak\u00f5la m\u00e4rgid v\u00f5ivad edasistes katesetes osutuda statistiliseks k\u00f5rvalekaldeks, mis suuremates andmemahtudes lahtub.<\/p>\n

Standardmudel on kasutusel olnud \u00fcle poole sajandi. Ta kirjeldab elementaarosakeste maailma \u00fclih\u00e4sti, kuid on ebat\u00e4ielik, sest maailmas on muis valdkonnis veel m\u00f5ndagi, mida ta kirjeldada ei suuda. Seet\u00f5ttu on f\u00fc\u00fcsikud kindlad, et kunagi tuleb standardmudel millegi veel parema vastu v\u00e4lja vahetada.<\/p>\n
