Creation of Two Charginos and Neutralino Via Different Propagators

We investigated the creation of two Charginos ( (cid:1)(cid:2) ± ) and neutralino ( (cid:1)(cid:2) (cid:4) ) owing to electron-positron annihilation via the process (cid:5) (cid:6) (cid:7)(cid:8) (cid:9) (cid:10) + (cid:5) (cid:12) (cid:7)(cid:8) (cid:13) (cid:10) → (cid:1)(cid:2) (cid:15)(cid:6) (cid:7)(cid:8) (cid:16) (cid:10) + (cid:1)(cid:2) (cid:17)(cid:12) (cid:7)(cid:8) (cid:18) (cid:10) + (cid:1)(cid:2) ℓ° (cid:7)(cid:8) (cid:21) (cid:10) and estimated the cross section for this interaction in the Minimal Supersymmetric Standard Model (MSSM). There are three gatherings of Feynman graphs which taken by the sorts of the propagators. Group (I) when (cid:1)(cid:2) and (cid:4) boson are propagators, Group (II) when (cid:1)(cid:2) (cid:4) and h (cid:4) (lighter Higgs boson) propagators and Group (III) (cid:1)(cid:2) (cid:4) and H (cid:4) Higgs boson) propagators, (cid:10) in group III At S interval (1000- 2100) Gev, the best value of σ is (cid:7) 0.072 (cid:10) Pb in-group (I). When masses of Charginos are m /0 12 = 700 GeV , m /0 67 = 700GeV and mass of neutralino is m 8(cid:2) ℓ9 = 800 GeV
