Production of Charged and Neutral Higgs Bosons with Charginos and Neutralinos through different Propagators in the MSSM

Abstract

In this work, the following reactions have been studied: $e^- e^+ \to H^- \widetilde{\chi}_{1}^+ \widetilde{\chi}_{1}^o$, $e^{-}e^{+}\to h\widetilde{\chi}_{1}^{+}\widetilde{\chi}_{1}^{-}$, $e^{-}e^{+}\to h\widetilde{\chi}_{1}^{o}\widetilde{\chi}_{1}^{o}$, $e^{-}e^{+}\to h H^{+} H^{-}$, where $\widetilde{\chi}_{1}^{\pm}$ is the chargino and $\widetilde{\chi}_{1}^{0}$ is the neutralino. $h$ represent the lightest neutral Higgs boson, and $H_3$ (sometimes refered to as $A$) is the pseudoscalar Higgs boson. The work went to calculate the differential cross section due to each Feynman diagram, then, the total cross section for each reaction is calculated according to a carefully used set of parameters. Results are graphed and tabulated. Comparisons between the obtained results are also given.
