Saynis yahano ka tirsan jaamacadda Adelaide oo ay weheliyaan koox cilmi baadhayaal ah oo caalami ah, ayaa horumar la taaban karo ka sameeyey daah-furka siraha arrimaha mugdiga ah, taas oo ka dhigan in 84% ka mid ah waxyaabaha koonku ka kooban yahay. Diirada-saarkoodu waxa uu ahaa qayb aragti ah oo loo yaqaan "photon madow," kaas oo laga yaabo in uu gacan ka geysto in la xakameeyo farqiga u dhexeeya walxaha madow iyo walxaha caadiga ah.
Walxaha mugdiga ah, walaxda qarsoon ee aan inta badan la garanayn, ayaa si adag loo aasaasay iyada oo loo marayo isdhexgalka. Si kastaba ha ahaatee, dabeecadeeda saxda ah ayaa wali sii socota inay ka fogaato physicists adduunka oo dhan. Mala-awaalka mugdiga ah ee sawir-qaadista, kaas oo tilmaamaya jiritaanka qayb weyn oo u dhaqma sidii portal u dhexeeya qaybta mugdiga ah iyo walxaha caadiga ah, ayaa kasbaday fahamka hal-abuurkan.
Professor Anthony Thomas, oo ah borofisar ku takhasusay cilmiga fiisigiska ee Jaamacadda Adelaide, ayaa sharaxaya, "Shaqadayadu waxay muujineysaa in mala-awaalka mugdiga ah ee photon-ka laga door bidayo mala-awaalka moodeelka caadiga ah ee macnaha 6.5 sigma, kaas oo ka kooban caddaynta helitaanka qayb." Daah-furkani waxa uu ina keenayaa hal tallaabo oo aanu ku fahmi karno dabeecadda maaddada mugdiga ah.
Maaddada mugdiga ahi aad ayey uga badan tahay maadada caadiga ah, iyada oo shan jeer ay ka badan tahay tirada caalamka ka jirta. Fiisigisyadu waxay u arkaan in wax badan oo ku saabsan walxaha mugdiga ah la kashifo inay tahay mid ka mid ah caqabadaha ugu waaweyn ee goobtooda. Sawirka mugdiga ah, qayb mala-awaal ah oo la xidhiidha qaybta qarsoon, ayaa awood u leh inay u adeegto sidii xoog sidaha walxaha mugdiga ah.
Si loo helo fikrado ku saabsan maaddooyinka mugdiga ah, kooxda saynisyahanadu waxay falanqeeyeen saamaynta photon-ka mugdiga ah uu ku yeelan karo natiijooyinka tijaabada ah ee habka firdhisanaanta qoto dheer. Habkani waxa uu ku lug leeyahay daraasaynta isku dhaca walxaha la dedejiyey ee tamarta aadka u sarreeya. Marka la baadho waxyaabaha ka soo baxa shilalkan, cilmi-baarayaashu waxay heli karaan macluumaad qiimo leh oo ku saabsan qaab dhismeedka adduunka subatomic.
Kooxdu waxay adeegsatay qaybta Jefferson Lab Angular Momentum (JAM) qayb qaybinta qaab dhismeedka falanqaynta caalamiga ah, iyaga oo wax ka beddelaya si loogu xisaabtamo suurtagalnimada sawir madow. Natiijooyinkooda ayaa shaaca ka qaaday in mala-awaalka mugdiga ah ee photon-ka uu ka doorbido mala-awaalka moodeelka caadiga ah, isagoo caddaynaya jiritaanka qaybtan.
Cilmi-baadhistan aasaaska u ah waxay furaysaa fursado cusub oo lagu sahaminayo dabeecadda qalafsan ee walxaha mugdiga ah. Fahamka maaddada mugdiga ah kaliya muhiim uma aha daah-furka siraha koonka laakiin sidoo kale horumarinta aqoontayada fiisigiska aasaasiga ah.
