Leptonic number violation signature arising from a $Z^{\mathrm{\prime }}$ model with non-diagonal leptonic couplings

Within the framework of a $Z^{\mathrm{\prime }}$ model with non-universal leptonic couplings, we analyze possible signatures of leptonic number violation effects at LHC. Results are described for leptonic energy distributions, both from its specific signature and events number, that could allow us to observe this class of models, under reasonable conditions at LHC.
