Charged right-handed Higgsino field contribution to the chargino mass   spectrum and inverse parameter problem in Left-Right Supersymmetric Models
  The contribution of the charged right-handed higgsino fields to the chargino mass spectrum in the context of the Left-Right Supersymmetric Model is studied. Analytical expressions for the chargino masses assuming arbitrary CP-violating phases are given. Also, the corresponding inverse parameter problem is studied. Analytical disentangling of some relevant parameters is presented. A general inversion algorithm, based on suitable measurement of cross-section type observables associated to chargino pair production in electron positron annihilation, is proposed.
