CP violating Tri-bimaximal-Cabibbo mixing
In view of the new data from the Daya Bay and RENO collaborations, King has
presented a very natural deformation of tri-bimaximal mixing. Here we show that
L/E flatness of the e-like event ratio in the atmospheric neutrino data, when
coupled with King's observation that the smallest neutrino mixing angle,
\theta_{13}, seems to be related to the largest quark mixing angle (the Cabibbo
angle \theta_C), leads to a CP violating tri-bimaximal-Cabibbo mixing. King's
tri-bimaximal-Cabibbo mixing follows as a leading order approximation from our
result.Comment: 6 page

Theory of Neutral Particles: Mclennan-Case Construct for Neutrino, Its Generalization, and a New Wave Equation
Continuing our recent argument where we constructed a FNBWW-type spin-
boson having opposite relative intrinsic parity to that of the associated
antiparticle, we now study eigenstates of the Charge Conjugation operator.
Based on the observation that if transforms as a
spinor under Lorentz boosts, then
transforms as a spinor (with a similar relationship existing between
and ; where with
the well known Wigner matrix involved in the operation of time
reversal) we introduce McLennan-Case type spinors.
Relative phases between and
, and
and , turn out to
have physical significance and are fixed by appropriate requirements. Explicit
construction, and a series of physically relevant properties, for these spinors
are obtained for spin- and spin- culminating in the construction of a
new wave equation and introduction of Dirac-like and Majorana-like quantum
fields.Comment: Revised and re-written version to appear in Int. J. Mod. Phys. A. At
present violations of various symmetries, such as C, P, and T, are assumed to
arise from interactions. It is argued that the violation is more fundamental
than that and is to be found at basic level of the representations of the
Lorentz group. Revtex 3.0 (20 pages
