Abstract

The cross‐sections for the process: e− (p1)e+ (p2) → χ̃i0 (p3)χ̆j0 (p4)Hl0 (p5) Have been calculated for all different situations, which are (1520) situations. Three different groups of Feynman diagrams are taken into account a‐ Production of Hl0 from different propagators (from 1–752 Feynman diagrams), b‐ Production of Hl0 from different legs when Z0 is the propagator (from 753–944 Feynman diagrams), c‐ Production of Hl0 from different legs when H0 is the propagator (from 945–1520 Feynman diagrams). The values of the cross‐sections have been calculated for different incident energy (S) which ranges from 500 to 2000 GeV and for different Higgs’ masses. The most probable mechanisms for such reaction are determined.
