Description
Summary:Within the framework of the Minimal Supersymmetric Standard Model, the decay of a polarized chargino (neutralino) into a polarized neutralino and a gauge boson in reactions χ ˜ i ∓ → χ ˜ j ∓ + W ∓ and χ ˜ i 0 → χ ˜ j 0 + Z are considered. Analytical expressions for the decay widths have been obtained with allowance for the chargino and neutralino polarized states. The neutralino longitudinal and transverse polarization degrees have been determined together with the asymmetry caused by initial chargino (neutralino) polarization. The dependence of these characteristics and the decay width on the chargino (neutralino) mass has been studied.
