Decomposition of weak hypercharge number and electroweak interaction model.

Abstract

The lack of simplicity of the weak hypercharge [ital Y] values in the standard electroweak model suggests the possibility that [ital Y] may not be a truly fundamental number and may be expressed as the sum of the baryon number, lepton number, [ital I][sub 3][sup [ital L]], and [ital I][sub 3][sup [ital R]]. Such an idea will lead to an SU(2)[sub [ital L]][times]U(1)[sub leptons][times]U(1)[sub baryon][times]U(1)[sub [ital R]] electroweak model, where the lepton and baryon numbers have short-range dynamical effects, and new weak neutral vector particles of unusual coupling properties arise.
