Maximal Neutrino Mixing and Maximal CP Violation
We propose a phenomenological model of lepton mixing and CP violation based on the flavor democracy of charge leptons and the mass degeneracy of neutrinos. A nearly bi-maximal flavor mixing pattern, which is favored by current data on atmospheric and solar neutrino oscillations, emerges naturally from this model after explicit symmetry breaking. The rephasing-invariant strength of CP or T viola...
متن کاملCp Symmetry Violation
The symmetry known as CP is a fundamental relation between matter and antimatter. The discovery of its violation by Christenson, Cronin, Fitch, and Turlay (1964) has given us important insights into the structure of particle interactions and into why the Universe appears to contain more matter than antimatter. In 1928, Paul Dirac predicted that every particle has a corresponding antiparticle. I...
متن کاملA Symmetry Approach to Cp Violation
One of the greatest challenges for particle physics in the 1990’s is understanding the broken symmetry of CP violation. It is now almost 30 years since the discovery in 1964 of the KL → 2π decay. What has happened since? Why has there been no significant new experimental input in this long period? The original KL → 2π decay experiment is described by two parameters ǫ and ǫ. Today ǫ ≈ its 1964 v...

متن کاملA Model of Cp Violation
It is shown that a two-Higgs doublet model with Vacuum CP Violation and Approximate Global U(1) Family Symmetries (AGUFS) may provide one of the simplest and attractive models in understanding origin and mechanisms of CP violation at the weak scale. The whole new interactions of the model are explicitly presented here. It is seen that CP violation can occur, after spontaneous symmetry breaking,...
