Higgs bosons production and decay at future $e^{+}{e}^{-}$ linear colliders as a probe of the B-L model

Abstract

We study the phenomenology of the light and heavy Higgs boson production and decay in the context of a $U(1{)}_{B-L}$ extension of the Standard Model with an additional $Z^{\prime }$ boson at future $e^{+}{e}^{-}$ linear colliders with center-of-mass energies of $\sqrt{s}=500-3000GeV$ and integrated luminosities of $\mathcal{L}=500-2000f{b}^{-1}$. The study includes the processes $e^{+}{e}^{-}\to (Z,Z^{\prime })\to Zh$ and $e^{+}{e}^{-}\to (Z,Z^{\prime })\to ZH$, considering both the resonant and non-resonant effects. We find that the total number of expected $Zh$ and $ZH$ events can reach 909,124 and 97,487, respectively, which is a very optimistic scenario and thus it would be possible to perform precision measurements for both Higgs bosons $h$ and $H$, as well as for the $Z^{\prime }$ boson in future high-energy and high-luminosity $e^{+}{e}^{-}$ colliders experiments. Our study complements other studies on the B-L model and on the Higgs-strahlung processes $e^{+}{e}^{-}\to (Z,Z^{\prime })\to Zh$ and $e^{+}{e}^{-}\to (Z,Z^{\prime })\to ZH$.
