The cross-section, in electron (e-) positron (e+) collision, are calculated over range of center of mass energy for the process. Four different group of Feynman diagrams are taken into consideration depending on the type of the propagator: i - Production of χ0 and H± when z0 and H0 are the propagators exchange. ii - Production of χ0 and H± when χ0 is a leg from electron or positron, and γ is the propagator. iii - Production of χ0 and H± when χ0 is a leg from electron and positron, and Z0 is the propagator. iv - Production of χ0 and H± when χ0 is a leg from electron or positron, and H0 is the propagator. Where (i, j = 1,2,3, and = 1,2,3,4) The cross section for each group is calculated according to a carefully selected set of parameters. These different possible (1155) situations are graphed and tabulated. The production mechanisms can be detected as:
