New 'Sterile' Fundamental Particle

Scientists find signs of a ‘sterile neutrino,’ a fundamental particle that shouldn’t exist.

A major physics experiment at the Fermi National Accelerator Laboratory near Chicago, observed a ghost particle that shouldn’t exist.

This could rewrite the rules of physics and solve the existence of dark matter, that makes up about 27 per cent of our Universe.

Scientists fired “beams of muon neutrinos at an oil tank to try and detect the presence of sterile neutrinos,” during the Mini Booster Neutrino Experiment, or MiniBooNE, in Chicago.

They detected far more electron neutrinos than predicted, a possible evidence of a revolutionary new elementary particle called the sterile neutrino.

Janet Conrad, a neutrino physicist at the Massachusetts Institute of Technology and a member of the MiniBooNE collaboration, said:

“I’m very excited about this result, but I am not ready to say ‘Eureka!’”
