Analytical expressions relating the fundamental parameters describing the chargino sector in the context of the Left-Right Supersymmetric model are constructed. A general complex extension of the real non-symmetric chargino mass matrix including all possible CP-violating phases is considered. The method used for such a effects is the projector formalism based on the explicit knowledge of two unitary matrices diagonalizing the chargino mass matrix. Some possible scenarios allowing us to extract analytical and numerical values for the unknown parameters are considered. Moreover, an algorithm allowing us to disentangle the fundamental parameters of the chargino sector, based on possible measurements of some class of cross-section observables related to the chargino pair production in e + e − annihilation processes, is described. Some comparisons with the corresponding results in the context of the Minimal Supersymmetric Standard Model are given. *

“…These scenarios are similar to the ones studied in Ref. [13] where they have been used to compare the predicted results for the neutralino masses in the left-right SUSY model and the MSSM. Thus, for both scenarios, we consider the coupling constant values g R g L g V 0:65, the gaugino parameters M L M V 0:0 GeV, and the mixing phases L 0.…”

“…To know the neutralino masses predicted by the present model, we can solve the characteristic equation associated with the Hermitian matrix H N y N. More precisely, the square root of the positive roots of this characteristic equation corresponds to the physical neutralino masses. The neutralino masses predicted by the present model are known only for the CP-conserving case under the limit of large M L;R or large jj [13], more precisely on the assumptions that jM L;R j M Z L , M R > M V , and 4g 2…”

We report exact analytical expressions relating the fundamental parameters describing the neutralino sector in the context of the left-right supersymmetric model. The method used for such effects is the projector formalism deduced without taking into account the Jarlskog's projector formulas. Also, expressions for the neutralino masses and the neutralino mixing matrix are determined . The results are compared with numerical and analytical ones obtained in similar scenarios in the context of the minimal supersymmetric standard model.
