Charged Higgs Pair Production in a General Two Higgs Doublet Model at $e^{+}{e}^{-}$ and ${\mu }^{+}{\mu }^{-}$ Linear Colliders

Abstract

In this paper, charged Higgs pair production through ${\ell }^{+}{\ell }^{-}\to H^{+}{H}^{-}$ where $\ell =e$ or $\mu$, is studied within the framework of a general Two Higgs Doublet Model (2HDM). The analysis is relevant to a future $e^{+}{e}^{-}$ or ${\mu }^{+}{\mu }^{-}$ collider operating at center of mass energy of $\sqrt{s}=500$ GeV. Two different scenarios of small and large $\alpha$ values is studied. Here $\alpha$ is the parameter which diagonalizes the neutral CP-even Higgs boson mass matrix. Within the Minimal Supersymmetric Standard Model (MSSM), cross section of this process is almost the same at $e^{+}{e}^{-}$ and ${\mu }^{+}{\mu }^{-}$ colliders. It is shown that at $e^{+}{e}^{-}$ colliders within a general 2HDM, cross section is not sensitive to the mass of neutral Higgs bosons, however, it can acquire large values up to several picobarn at ${\mu }^{+}{\mu }^{-}$ colliders with the presence of heavy neutral Higgs bosons. A scan over Higgs boson mass parameter space is performed to analyze the effect of large masses of neutral Higgs bosons involved in the s-channel propagator and thus in the total cross section of this process.
