A chiral electroweak model which accounts for spontaneous CP breaking is proposed. Under the requirement of realistic quark mixing matrices and as a result of a detailed study of the Higgs potential, CP-violating relative phases among the vacuum expectation values of the scalars coupled to the fermions are seen to emerge. The strong CP problem is solved without any restrictive assumptions. The phenomenological implications of the neutral-kaon system are analyzed, and a new physics in the Higgs sector is proposed to render ‖ΔscrS‖=2 enhanced interactions consistent with a not too high value of parity-breaking scale.

Abstract
A chiral electroweak model which accounts for spontaneous CP breaking is proposed. Under the requirement of realistic quark mixing matrices and as a result of a detailed study of the Higgs potential, CP-violating relative phases among the vacuum expectation values of the scalars coupled to the fermions are seen to emerge. The strong CP problem is solved without any restrictive assumptions. The phenomenological implications of the neutral-kaon system are analyzed, and a new physics in the Higgs sector is proposed to render ‖ΔscrS‖=2 enhanced interactions consistent with a not too high value of parity-breaking scale.File in questo prodotto:
