Abstract:The Z → γγ and Z → gg decays are studied in the context of the renormalizable version of the Standard Model Extension. The CP T -odd ψγ 5 / bψ bilinear interaction, which involves the constant background field bα and which has been a subject of interest in literature, is considered. It is shown that the Z → γγ and Z → gg decays, which are strictly zero in the standard model, can be generated radiatively at the one-loop level. It is found that these decays are gauge invariant and free of ultraviolet divergences… Show more
