ONE-LOOP OFF-SHELL DECAY H∗ → ZZ AT FUTURE COLLIDERS
We present one-loop formulas for contributing to the HZZ vertex in ’t Hooft-Veltmangauge within Standard Model framework. One-loop off-shell Higgs decay rates to Z-pair areinvestigated in both unpolarized and longitudinal polarization for Z bosons in final state. Thecorrections are range of 7% to 8.4% when we vary the off-shell Higgs mass from 200 GeV to500 GeV. In applications, we study off-shell Higgs decay H ∗ → ZZ in the Higgs productions atfuture colliders such as the signal processes γ ∗ (Q2 )γ → H ∗ → ZZ and e− γ → e− H ∗ → e− ZZ areanalyzed.
