Abstract: By introducing a set of new triplet leptons with nonzero hypercharge thatcan Yukawa couple to their Standard Model counterparts, new sources oftree-level flavor changing currents are induced via mixing. In this work, westudy some of the consequences of such new contributions on processes such asthe leptonic decays of gauge bosons, $\ell ightarrow 3\ell-$ and $\ell ightarrow \ell- \gamma$ which violate lepton flavor, and mu-e conversion inatomic nuclei. Constraints are then placed on the parameters associated withthe exotic triplets by invoking the current low-energy experimental data.Moreover, the new physics contribution to the lepton anomalous magnetic momentsis calculated.
