Neutrino mass and new physics

Understand

Implications of the recent results on neutrino masses and mixing to underlying new physics are considered.

• Various approaches to physics behind neutrino mass are described which include the tri-bimaximal mixing and flavor symmetries, the quark-lepton complementarity and weak complementarity, the quark-lepton universality and unification.
• Some recent results from string phenomenology are discussed and the issue of model building versus "string engineering" is outlined.
