CERN and NAL groups claim evidence for neutral currents
DOI: 10.1063/1.3128313
Two experiments, one at CERN and the other at the National Accelerator Laboratory, are showing evidence for the existence of neutral currents. They are finding events in which a neutrino interacts with a nucleon and, instead of producing a muon or an electron, yields hadrons without a charged lepton. Because of the recent interest in theories that attempt to unify the weak and electromagnetic interactions, such as those proposed by Steven Weinberg (
