Z ′ Resonance and Associated Z h Production at Future Higgs Boson Factory: ILC and CLIC

Abstract EN

We study the prospects of the B - L model with an additional Z ′ boson to be a Higgs boson factory at high-energy and high-luminosity linear electron positron colliders, such as the ILC and CLIC, through the Higgs-strahlung process e + e - → ( Z , Z ′ ) → Z h , including both the resonant and the nonresonant effects.

We evaluate the total cross section of Z h and we calculate the total number of events for integrated luminosities of 500–2000 fb−1 and center of mass energies between 500 and 3000 GeV.

We find that the total number of expected Z h events can reach 106, which is a very optimistic scenario and it would be possible to perform precision measurements for both Z ′ and Higgs boson in future high-energy e + e - colliders experiments.
