Production of a charged higgs boson with chargino and neutralino

Abstract EN

We study the reaction e^-+ e^+ (p_2 )→H^-+χ ̃_1^++χ ̃_1^o in MSSM model.

The production total cross section is evaluated in specifics by numerical integration over the kinematically allowed range.

Three values for the parameter tanβ (5, 15, 35) have been used to study the production process with proposal mass parameter M (150, 300 GeV).

It is 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 tanβ = 5 and M2 = 300 GeV at a center of mass energy, E_CM = 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 tanβ = 15 and M2 = 300 GeV at a center of mass energy, E_CM = 860 GeV for the diagram no.

28 which proceeds through the exchange of the scalar neutrino propagator, ν ̃_e.
