Sterile neutrino

The sterile neutrino is a hypothetical elementary particle that is subject only to the fundamental interactions of the standard model of gravity. It is a right-handed neutrino and its left-handed super affiliate, also called sterile sneutrino ( the normal neutrino is left-handed and right-handed sneutrino normal ).

Such particles belong to a singlet representation of the strong and the weak interaction; their weak hypercharge, weak isospin and their electric charges are each zero. If they are heavy enough, they could explain the ( cold or warm ) dark matter. In a grand unified theory (GUT ) such as the Georgi - Glashow model interacting via gauge bosons that. During ordinary, ie relatively low energies are strongly suppressed due to their extremely high mass

On 11 April 2007, researchers reported the Mini - Boone experiment at Fermilab that they had found no evidence for the existence of sterile neutrinos. Some recent results and analyzes have, however, been a slight support for the assumption of the existence of sterile neutrinos.
