Abstract.
In supersymmetric grand unified theories, light higgsino multiplets generally exist in addition to the familiar chargino/neutralino multiplets of the minimal supersymmetric extension of the Standard Model. The new multiplets may include doubly charged states \(\tilde\Delta^{\pm\pm}\) and \(\tilde\delta^{\pm\pm}\). We study the properties and the production channels of these novel higgsinos in \(e^+e^-\) and \(\gamma\gamma\) collisions, and investigate how their properties can be analyzed experimentally.
