| We calculate the Higgs masses and production cross section in a class of minimal super-symmetric models that contain an extra U(1) ′ gauge symmetry. We address the effect of CP violation, originating in the scalar top quark mass matrix, on the Higgs masses at the one-loop level. We also derive general expressions for the Higgs couplings that are relevant for their production. For the numerical analysis of the couplings and cross section, we focus on the models that yield a relatively light and leptophobic Z′ boson. We use the current experimental lower bound on the lightest Higgs mass, and the smallness of the Z − Z′ mixing angle to constrain our parameter space. |
