Search for intermediate boson production in high-energy neutrino interactions

This paper reports that if weak interaction are mediated by a boson W, it should be produced in high-energy neutrino experiments, provided its mass is not too high. The reaction would be νμ + Z → W+ + μ- + Z where Z is a nucleus or a proton. The boson would then decay within 10-18 sec into a neutrino and a charged lepton or into a system of pions and kaons W+ → μ+ + νμ; W+ → e+ + νe; W+ → pions and/or kaons. The rate expected to be almost equal, whereas the rate is unknown. Previously these reactions have been searched for by Danby et al. in the Columbia neutrino spark chamber. In the CERN neutrino spark chamber, we have made a systematic search for lepton pairs, μ-μ+ and μ-E+ which would show up as a result of reactions
