Full one-loop supersymmetric corrections to charged Higgs boson pair production in $\gamma \gamma$ collisions

Abstract

The complete one-loop electroweak corrections to charged Higgs boson pair production in $\gamma \gamma$ collision mode at linear colliders in the minimal supersymmetric standard model (MSSM), are calculated in this paper. We discuss the dependence of the corrections to the subprocess $\gamma \gamma \to H^{+}{H}^{-}$ on the related parameters, such as the colliding energy, charged Higgs boson mass $M_{H^{\pm }}$ and some supersymmetric parameters $\tan \beta$, $M_{SUSY}$ and gaugino mass parameter $M_2$. We find that the corrections generally reduce the Born cross sections and the relative one-loop corrections to both the subprocess typically in the range of -10% to -30%. We also present the numerical results at the SPS1a' point from the SPA project. We conclude that the full one-loop electroweak corrections to subprocess $\gamma \gamma \to H^{+}{H}^{-}$ and the parent process $e^{+}{e}^{-}\to \gamma \gamma \to H^{+}{H}^{-}$ are significant and therefore should be considered in precise analysis of charged Higgs boson pair productions via $\gamma \gamma$ collision at future linear colliders.
