The 3–3–1 Model with RH Neutrinos and Associated ZH Production at High-Energy ${\bf \textit{e}}^{+}{\bf \textit{e}}^{-}$ Collider

Abstract

In the context of SU(3) C ⊗ SU(3) L ⊗ U(1) X (3–3–1) model with right-handed neutrinos, we study the Higgsstrahlung process e + e − →ZH and calculate the cross section of this process at leading order. Our numerical results showed that the production cross sections for this process can be significantly large as $M_{Z'}\approx \sqrt{s}$ . With reasonable values of the Z′ mass M Z′, Z′ exchange can generate large corrections to the cross sections of this process, which might be detected in the future high-energy linear e + e − collider experiments.
