Production of a Charged Higgs Boson with Chargino and Neutralino

Abstract

The reaction − + + ( ) → − + � + + � in MSSM model is studied. The production total cross section is evaluated in specifics by numerical integration over the kinematically allowed range. Three values for the parameter (5, 15, 35) have been used to study the production process with a proposal mass parameter M (150, 300 GeV). It was found that the dominant production can reach about 10 −4 pb in the allowed range of parameters. The maximum cross section achieved reaches the value 1.6853 × 10 −5 pb for = 5 and = 300 GeV at a center of mass energy, = 880 GeV for the diagram no. 2 which proceeds through the photon propagator, γ. A maximum of 1.0836 × 10 -4 pb was obtained for = 15 and = 300 GeV at a center of mass energy, = 860 GeV for the diagram no. 28 which proceeds through the exchange of the scalar neutrino propagator, � . For = 35 and = 300 GeV at a center of mass energy, = 900 GeV, the cross section obtained, reached the value 1.8623×10 −4 pb.
