Abstract
An SU(2)×U(1)×SU(2)′ model is considered with symmetrical isovector gauge couplings. Heavy fermions with weak interactions are assigned to SU(2)′. The symmetry is broken by scalar multiplets with respective vacuum expectation values . The predictions are specified by one additional weak angle. The lightest weak bosons lie in the ranges GeV and GeV. The smallness of the additional neutral-current interaction is explained.
