The Standard Model of particle purgative is the serious description we have of how particles and forces interact in the world . But it is by far not perfect , and over the years novel discoveries have indicated that there ’s much more out there in the universe .
A group of European physicist has now suggested an telephone extension to the Standard Model , and they claim it resolve some of itsbiggest problem , like the nature of dark matter , how neutrinos commute from one character to the others , and why the cosmos is made of affair and not anti - affair .
The scientist have proposed that these and other problem can be solved by the addition of six novel particle to the Standard Model . Three are right - handed neutrinos , which are just like regular neutrinos except they spin in the opposite direction . Another is a new fermion , which decays into quark cheese and disappears in the advanced - day universe , and the other two are new mote that produce an interactive field .
The team take that this Modern field of operation interacts with the Higgs field ( which gives particles mass ) and , according to their model , it can generate the exponential expansion the cosmos experienced in its first instants , which is known ascosmic rising prices .
While the propose theater is crucial to explaining what happened just after the Big Bang , one of the field ’s particles might bring a theatrical role in the entire chronicle of the universe : It could be dark matter . At the very commencement , their field generates bombastic quantities of “ axions ” , very swooning speck that do n’t interact much with the “ standard ” particle . The properties they have found in their model , which they dubbed SMASH ( Standard Model Axion Seesaw Higgs ) , reach these axions a good friction match for what cosmologists believe dark matter is made of .
SMASH was announced in a newspaper , available to learn online onarXiv , and although it explains several missing features of the Standard Model , it has not been proven yet . The particles predicted by the researchers could soon be found by several current or coming experiments like CULTASK or MADMAX .
“ The good thing about the possibility is that it can be test or watch within the next 10 years or so , ” co - author Andreas Ringwald , from the German Electron Synchrotron ( DESY ) in Germany , toldNew Scientist . “ The battle is open . ”
With experiment operate all over the world , the pursuit for improving the Standard Model is on . But we do n’t live when or even if we ’ll get there .
