Neutrinos and collider physics

We review the collider phenomenology of neutrino physics and the synergetic aspectsat energy, intensity and cosmic frontiersto test the new physics behind the neutrino mass mechanism. In particular,wefocus on see saw models within the minimal setup as well as with extended gauge and/or Higgs sectors, and on supersymmetric neutrino mass models with seesaw mechanism and with R-parity violation. In the simplest type-I seesaw scenario with sterile neutrinos, we summarize and update the current experimental constraints on the sterile neutrino mass and its mixing with the active neutrinos.We also discuss the future experimental prospectsoftesting the seesaw mechanism at colliders and in related low-energy searches for rare processes, such as lepton flavor violation and neutrinoless double beta decay. The implications of the discovery of lepton number violation at the Large Hadron Collider for leptogenesis are also studied.
