Abstract
In the current work we investigated the production of neutral Higgs boson (H_l^°) and two charged Charginos (χ ̃_i^+,χ ̃_j^-) owing to electron-positron annihilation via different propagators for the process e^- (p_1 )+e^+ (p_3 )→χ ̃_i^+ (p_2 )+ χ ̃_j^- (p_4 )+H_l^° (p_5 ) and in the Minimal Supersymmetric Standard Model (MSSM), the cross sections for this interaction were estimated. Five groups of 240 probabilities from Feynman diagrams are taken by different propagators. Group (I) when h^o and Z^o bosons are propagators, Group (II) when Z^o and h^o bosons are propagators, Group (III) when〖 h〗^oand h^o (Lightest Higgs boson) bosons are propagators, Group (IV) Z^o and Z^o bosons are propagators and Group (V) χ ̃^o and Z^oboson are propagators where i=j=1,2 and l=1,2,3.
We calculated the process's production cross-sections as a function of mass center energy, and determined the best cross-section based on all considerations of the (MSSM).At S interval (1600- 3500) Gev, the best value of σ is ( 7.3934×10^(-4) ) Pb in-group (IV). When masses of Charginos are m_(χ ̃_j^- )=900 GeV, m_(χ ̃_i^+ )=700GeV and mass of neutral Higgs boson is 〖 m〗_(H_l^° ) =140 GeV
