Neutrino mass and new physics
Preprint
- 9 October 2009
Abstract
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.Keywords
