Abstract: 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.
