英文摘要: The production of the lightest chargino pair from gluon-gluon fusion is studied in the minimal supersymmetric standard model (MSSM) at proton-proton colliders. We find that with the chosen parameters, the production rate of the subprocess can be over 2.7 fb when the chargino is Higgsino-like, and the corresponding total cross section in proton-proton colliders can reach 56 fb at the CERN Large Hadron Colider (LHC) in the CP-conserving MSSM. It shows that this loop mediated subprocess can be competitive with the standard Drell-Yan subprocess in proton-proton colliders, especially at the LHC. Furthermore, our calculation shows it would be possible to extract information about some CP-violating phase parameters if we collected enough chargino pair events. [S0556-2821(99)08519-7].
