World's smallest neutrino detector finds big physics fingerprint
DOE/Oak Ridge National Laboratory
The research, performed at ORNL’s Spallation Neutron Source (SNS) and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago, but never seen. The one-of-a-kind particle physics experiment at Oak Ridge National Laboratory was the first to measure coherent scattering of low-energy neutrinos off nuclei, said ORNL physicist Jason Newby, technical coordinator and one of 11 ORNL participants in COHERENT, a collaboration of 80 researchers from 19 institutions and 4 nations.
