    • Abstract

       

      We construct a model of renormalizable electroweak interaction with (V+A) strangeness-changing charged current in the framework of the minimal spontaneously broken SU2 ⊗ U1 gauge theory, taking our motivation from the recently reported measurement of the electron asymmetry in polarizedΣ-hyperonβ-decay by Keller and co-workers. The model avoids strangeness-changing but admits charm-changing pieces in the neutral current. Several phenomenological consequences of the model are discussed together with a comparison with the standard model of electroweak interaction.
