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.
