摘要

The lighter chargino three body decays1~±→10ff’ via the W boson and the charged Higgs boson H± were studied in the R-parity conserved Minimal Supersymmetric Standard Model(MSSM).We treat 1~± decays as production and decay of W± and H±:i.e.,1~±→10W±(H±)→10ff’.Both higgsinolike and wino-likev1decays 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 fromv1decays is discussed.It will offer important information about the chargino and neutralino sector,as well as the charged Higgs sector in the MSSM.
