Littlest Higgs Model and Associated ZH Production at High Energy e+e- Collider

  • In the context of the littlest Higgs (LH) model, we consider the Higgs strahlung process e+e-→ZH. We find that the correction effects on the process mainly come from the heavy photon A′. If we take the mixing angle c in the range of 0.85—1, the contributions of the heavy gauge boson Z′ can not be neglected. In most of the parameter space, the deviation of the total production cross section σ tot from its SM value is larger than 5%, which may be observable in the future high energy e+e- collider (LC) experiments. The future LC experiments could test the LH model by measuring the cross section of the process e+e-→ZH.

Abstract: In the context of the littlest Higgs (LH) model, we consider the Higgs strahlung process e+e-→ZH. We find that the correction effects on the process mainly come from the heavy photon A′. If we take the mixing angle c in the range of 0.85—1, the contributions of the heavy gauge boson Z′ can not be neglected. In most of the parameter space, the deviation of the total production cross section σ tot from its SM value is larger than 5%, which may be observable in the future high energy e+e- collider (LC) experiments. The future LC experiments could test the LH model by measuring the cross section of the process e+e-→ZH.
