Reactionν+p→ν+μ++μ−+pin a Six-Fermion Coupling Theory

Abstract

A theory in which the hypothetical intermediate boson of weak interactions interacts strongly with hadrons becomes a theory with a six-fermion coupling in the limit that the mass of the boson is very large. To facilitate setting an upper limit on such couplings in high-energy neutrino experiments, we give here the theoretical muon spectra for the reaction $\nu +p\to \nu +{\mu }^{+}+{\mu }^{-}+p$ calculated for a typical six-fermion interaction. A comparison is also made with the muon spectra predicted from $V-A$ theory, and a rough upper limit on the coupling constant is made using data from the CERN neutrino experiment.
