Abstract

This letter presents a phenomenological analysis for the lepton (l_i) decaying into l_j l_k l_k, l_j π⁺ π^- considering family non-universal couplings as source of the lepton flavor-violating (LFV) currents and a new neutral gauge boson (Z') as mediator in the flavor-changing. The most viable g_V^f_if_J and g_A^f_if_j couplings are reported as long as derive new bounds for the M_Z' by using current results from LHC and a phenomenological analysis.
