Neutrino reactions and restrictions on the O(4) × U(1)-gauge theory of weak and electromagnetic interactions

Abstract

In this paper we have analysed and restricted the freedom of constructing gauge models of Pais type, based on the symmetry group O(4) × U(1) using the latest experimental data from neutrino reactions. The hadrons are made out of the fractionally charged Gell-Mann-Zweig quarks. The left-handed quarks and leptons are restricted to (a) 4-vector (b) 4-spinor and (c) adjoint representations of O(4). The right-handed quarks and leptons are taken as scalars of O(4). It is found that the model based on 4-spinorL-leptons and 4-spinorL-quarks agrees the best with the known phenomenology of weak interactions.
