The production of a chargino pair in muon colliders (I)
Within the framework of the Minimal Supersymmetric Standard Model, the process of the production of a pair of charginos in polarized muon-antimuon collisions is considered. Taking into account arbitrary polarizations of the pair, as well as the longitudinal or transverse polarization of the chargino, general expressions for the cross sections of the process are obtained. The longitudinal and transverse spin asymmetries caused by the polarizations of the pair, as well as the degrees of transverse and longitudinal polarization of the chargino, are determined. The angular and energy dependences of the polarization characteristics and the effective cross section are studied in detail.
