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: $e^{-}{e}^{+}\to H^{-}{\tilde{\chi }}_1^{+}{\tilde{\chi }}_1^o$, $e^{-}{e}^{+}\to h{\tilde{\chi }}_1^{+}{\tilde{\chi }}_1^{-}$, $e^{-}{e}^{+}\to h{\tilde{\chi }}_1^o{\tilde{\chi }}_1^o$, $e^{-}{e}^{+}\to h{H}^{+}{H}^{-}$, where ${\tilde{\chi }}_1^{\pm }$ is the chargino and ${\tilde{\chi }}_1^0$ 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.
