CERN has afford the green light to a new experiment , in the hope of detect a hypothetical particle that could potentially explain why the universe is made of matter or else of antimatter .
The experimentation is calledSHiP(Search for Hidden Particles ) , and it willl be instal at CERN by 2026 , with an expected cost of about $ 200 million ( £ 140 million ) . But before expression of the instrument can set out , each member state take to O.K. the project .
SHiP will look for uninspired neutrino , a suppositional subatomic particle that interacts super weakly , if at all , with the ordinary issue we are made of . So far we have detect three types , or “ flavors , ” of neutrino : electron , muon , and tau neutrinos . While the different flavors have different properties , the neutrino are capable to interchange from one to the other , a phenomenon call oscillation .
infertile neutrinos could be produced by this kind of cycle . The aseptic neutrino that are going to be hound at CERN belong to a specific grouping call Heavy Neutral Leptons . They are importantly more massive than the flavored salmagundi and , unlike their wanton counterpart , could give us clues to the potency of issue over antimatter in the universe .
TheStandard Model of particle physicsis the theory that connects three of the four fundamental forces ( electromagnetism , strong nuclear effect , and weak atomic force ) and fundamental particles . It forecast the existence of the top quark , tau neutrino , and Higgs boson before they were detected . In the Standard Model , neutrinos are massless , but since it was machinate , we have discovered they do have mass ( albeit very little ) . This imply that the Standard Model is limited and there ’s yet more physics to uncover .
" Finding a light sterile neutrino would be a Nobel prize discovery , but it would n’t solve the problems of the Standard Model , " Andrey Golutvin , a SHiP spokeperson , enjoin toPhysics World .
In the Modern experimentation , high - saturation proton beam of light produced by CERN’sSuper Proton Synchrotronwill be blast at a newfangled tungsten - molybdenum object , which will generate a cascade of mote check charm quarks . These quark crumble into active neutrinos , which might then oscillate into heavy unimaginative neutrinos .
uninventive neutrinos are not only interesting from a particle physics degree of view , but from an astrophysical one as well . If they are proven to live , they could be the particles that dark matter is made of , and they might also be responsible for several events in the moments after the Big Bang .
