Z' Resonance and Associated Zh Production at Future Higgs Boson Factory: ILC and CLIC

Abstract

We study the prospects of the 𝐵 − 𝐿 model with an additional 𝑍' boson to be a Higgs boson factory at high-energy and highluminosity linear electron positron colliders, such as the ILC and CLIC, through the Higgs-strahlung process 𝑒+ 𝑒− → (𝑍, 𝑍') → 𝑍ℎ, including both the resonant and the nonresonant effects. We evaluate the total cross section of 𝑍ℎ and we calculate the total number of events for integrated luminosities of 500 –2000fb−1 and center of mass energies between 500 and 3000GeV. We find that the total number of expected 𝑍ℎ 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.
