Grand Unification of Flavor Mixings
An origin of flavor mixings in quark and lepton sectors is still a mystery,
and a structure of the flavor mixings in lepton sector seems completely
different from that of quark sector. In this letter, we point out that the
flavor mixing angles in quark and lepton sectors could be unified at a high
energy scale, when neutrinos are degenerate. It means that a minimal flavor
violation at a high energy scale can induce a rich variety of flavor mixings in
quark and lepton sectors at a low energy scale through quantum corrections.Comment: 5 pages, 12 figures, references added, version to appear in EP
The Last Neutrino Mixing angle theta13
Among the still unmeasured neutrino properties, the third neutrino mixing
angle, theta13, is likely to be the one we will next find out. In this
contribution, first a brief summary of the limits and the preliminary
measurements of this angle is given. Second a critical assessment of a widely
used formula connecting two- and three-flavor evolution is provided.Comment: Proceedings of "Nuclear Physics in Astrophysics V, April 2011",
