We investigate herein the phenomenology of decay in a scenario of the class of extended models with non-sterile right-handed (RH) neutrinos at electroweak (EW) scale proposed by P. Q. Hung. The field content of the standard model (SM) is increased by introducing for each SM fermion a corresponding mirror partner with the same quantum numbers along with opposite chirality. Light neutrino masses are generated via the type I seesaw mechanism, and it is also proved to be relevant to low energy within the EW scale of RH neutrino masses. We introduce the model and derive the branching ratio of the
decay at one-loop approximation with the participation of W gauge boson and neutral and singly charged Higgs scalars. We then set constraints on relevant parameters and predict the sensitivity of the decay channel under the present and future experiments.
