Right–right–left extension of the Standard Model

Abstract

A right–right–left extension of the Standard Model is proposed. In this model, SM gauge group [Formula: see text] is extended to [Formula: see text]. The gauge symmetries [Formula: see text], [Formula: see text] are the mirror counterparts of the [Formula: see text] and [Formula: see text], respectively. Parity is spontaneously broken when the scalar Higgs fields acquire vacuum expectation values (VEVs) in a certain pattern. Parity is restored at the scale of [Formula: see text]. The gauge sector has a unique pattern. The scalar sector of the model is optimum, elegant and unique.
