DOUBLY-CHARGED HIGGSINO CONTRIBUTION TO THE DECAYS MU-]E-GAMMA AND MU-]3E AND TO THE ANOMALOUS MAGNETIC-MOMENT OF THE MUON DELTA-A(MU) WITHIN THE LEFT-RIGHT SUPERSYMMETRIC MODEL

We present a detailed and complete calculation of the doubly charged H iggsino contribution to the decays mu-->e gamma and mu-->3e and to the anomalous magnetic moment of the muon Delta a(mu) within the left-rig ht supersymmetric model. We include the mixing of the scalar partners of the left-and right-handed leptons, and show that it leads to a stro ng enhancement of the decay modes in certain scenarios. We find that t he contribution of the doubly char ed Higgsino can be close to the kno wn experimental values and is reachable by future experiments.
