e+e− → (hA) → bbbb in Abelian extended supersymmetric standard model

We discuss the e+e− → (hA) → bbbb cross section in an Abelian extended supersymmetric SM. We work in that minimum of the scalar potential for which Higgs trilinear coupling is greater than the soft mass parameters. We find that next-to-lightest Higgs gives the essential contribution to the cross section in the small Z - Z′ mixing angle and leptophobic Z′ limit.
