| 摘 要： | The lighter chargino three body decays ～χ±1→～χ0 1ff ′ via the W^± boson and the charged Higgs boson H^± were studied in the R-parity conserved Minimal Supersymmetric Standard Model （MSSM）. We treat ～χ±1 decays as production and decay of W^± and H^± i.e.,～χ±1→～χ01W^±（H^±） → χ0 1ff ′. Both higgsino- like and wino-like ～χ±1 decays were well investigated. These decays are calculated at 1-loop level and the loop corrections are found to be less than three percent. The signal of the charged Higgs H^± production from ～χ±1 decays is discussed. It will offer important information about the chargino and neutralino sector, as well as the charged Higgs sector in the MSSM. |

| Abstract: | The lighter chargino three body decays $tilde{chi }_1^pm rightarrow tilde{chi }_1^0 f f^prime $ via the $W^pm $ boson and the charged Higgs boson $H^pm $ were studied in the R-parity conserved Minimal Supersymmetric Standard Model (MSSM). We treat $tilde{chi }_1^pm $ decays as production and decay of $W^pm $ and $H^pm $ : i.e., $tilde{chi }_1^pm rightarrow tilde{chi }_1^0 W^pm (H^pm ) rightarrow tilde{chi }_1^0 f f^prime $ . Both higgsino-like and wino-like $tilde{chi }_1^pm $ decays were well investigated. These decays are calculated at 1-loop level and the loop corrections are found to be less than three percent. The signal of the charged Higgs $H^pm $ production from $tilde{chi }_1^pm $ decays is discussed. It will offer important information about the chargino and neutralino sector, as well as the charged Higgs sector in the MSSM. |
