Flavor physics is fundamental for testing the standard model of particle
physics and could be the key for discovering new physics. Nowadays, this
kind of processes, observed in neutrino oscillations, give us the clearest
evidence of the fact that the Standard Model of fundamental interactions
needs to be modified. Some of the most popular theories that try to asses
this issue postulate the existence of new heavy right-handed neutrinos,
with masses in the energy range that the LHC experiment is currently
exploring. We study the connection between the possible existence of these
neutrinos and lepton flavor physics. We consider the inverse seesaw model
as a particular realization of a low scale seesaw model and analyze its
lepton flavor violating phenomenology, in particular the Higgs and Z boson
decays to two leptons of different flavor. Moreover, we also explore the
possibility of directly producing these new heavy neutrinos at the LHC.
