ABSTRACT In the framework of the Minimal Supersymmetric Standard Model, the processes of annihilation of an arbitrarily polarized lepton-antilepton pair into a pair of charginos are considered: 𝓁 -+𝓁 + → χ̃𝑖- + χ̃𝒋+. A general expression is obtained for the cross section of the process in the case of arbitrarily polarized initial particles. The angular and polarization characteristics of the process have been studied in detail. In particular, it is shown that the asymmetry arising in the interaction of longitudinally polarized electrons with unpolarized positrons is equal in magnitude and opposite in sign of the asymmetry arising in the interaction of polarized positrons with unpolarized electrons. Keywords: Minimal Supersymmetric Standard Model, Standard Model, lepton-antilepton pair, chargino, longitudinal polarization, transverse polarization.
