Scientists 99 % certain sterile neutrino non-existentWASHINGTON — Scientists said Monday they are now “99 percent” certain that a hypothesized particle known as the “sterile neutrino” does not exist after analyzing two years’ worth of data from an icy particle detector at the South Pole. As a result, they concluded that there is 99 percent certainty the sterile neutrino hinted at by previous experiments is not real. Known as the “sterile neutrino,” the hypothesized particle would not interact at all with matter except, possibly, through gravity. However, the striking feature associated with the sterile neutrino was nowhere to be found, said Halzen, also a professor of physics at the University of Wisconsin-Madison. In this range, Halzen said, sterile neutrinos would produce a very distinctive signature.
