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.
