Determining neutralino parameters in Left-Right Supersymmetric Models
  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 a effects is the projector formalism deduced without take into account the Jarlskog's projector formulae. 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.
