Daya Bay places new limit on sterile neutrinos

The Daya Bay experiment, famous for studying neutrino mixing, is branching into a new area of neutrino physics. The experiment that produced the latest big discovery about ghostly particles called neutrinos is trying its hand at solving a second neutrino mystery. The Daya Bay Reactor Neutrino Experiment reported in Physical Review Letters today that it has narrowed the region in which the most elusive kind of neutrino, the sterile neutrino, might exist. Located in southern China, the experiment ...
