We conduct a detailed analysis of the phenomenology of two predictive see-saw scenarios which lead to the Quark-Lepton Complementarity relation θ12+θC = π/4. The neutrino mixing observables and their correlations, neutrinoless double beta decay, lepton flavor violating decays such as μ → eγ and leptogenesis are discussed. The features which allow to distinguish the scenarios are identified.

I argue that muon lepton flavor violating (LFV) processes (such as μ → eγ and μ → e conversion in nuclei) provide a useful diagnostic tool to determine whether or not the effective neutrino mass can be safely extracted from the rate of neutrinoless double beta decay.

Unique Capability

Same-sign lepton collisions in the TeV energy range may well have the unique capability to search for clear signals for the exchange of heavy Majorana neutrinos. Lepton-flavor-violating transitions e−e−→W−W− can thus contribute to the understanding of two unsolved riddles in particle physics: the neutrino mass problem and the question of the Dirac or Majorana character of heavy neutrinos. This search is not similarly accessible to such effects as neutrinoless double beta decay. The resulting experimental signatures are hard to miss.

With the historic discovery of the Higgs boson our picture of particle physics would have been complete were it not for the neutrino sector and cosmology. I briefly discuss the role of neutrino masses and mixing upon gauge coupling unification, electroweak breaking and the flavor sector. Time is ripe for new discoveries such as leptonic CP violation, charged lepton flavor violation and neutrinoless double beta decay. Neutrinos could also play a role in elucidating the nature of dark matter and cosmic inflation.

Superheavy neutrinos can, via the seesaw model, provide a mechanism for lepton number violation. If they are combined with flavor violation as characterized by the Froggatt–Nielsen mechanism, then the phenomenology for the neutrinos in oscillation experiments, neutrinoless double beta decay, and other experiments can be described by a relatively few number of parameters. We describe the low-energy neutrino mass matrix and show that the results are consistent with currently available data.
