World's smallest neutrino detector finds big physics fingerprint

(DOE/Oak Ridge National Laboratory) After more than a year of operation at the Department of Energy's Oak Ridge National Laboratory (ORNL), the COHERENT experiment, using the world's smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter. The research, performed at ORNL's Spallation Neutron Source and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by
