Production of charged Higgs-Bosons and Z- boson

By using the minimal supersymmetric extension of the standard model (MSSM), The cross-sections of the electron and positron scattering have been studied as a function of center-of-mass energy with the aid of feynman diagrams to produce charged Higgs boson and neutral Z-boson. The cross-sections of the reaction have been calculated through different models of interaction. The main conclusions can be summarized as follows: it is found that the production cross-section of reaction is most likely to happen through the exchange propagator Z.H..; the emission of z-boson from the initial legs through Z-boson or γ-photon propagator. The most dominant one is the case of the emission of z-boson from the initial legs and it could be detected at an energy of s≡ 750 GeV at a value of the order of ∼ 1 f barn
