A Novel Origin of CP Violation
Abstract. We propose the complex group theoretical Clebsch-Gordon coefficients as a novel origin of CP violation. This is manifest in our model based on SU(5) combined with the double tetrahedral group, T ′. Due to the presence of the doublet representations in T ′, there exist complex CG coefficients, leading to explicit CP violation in the model, while the Yukawa couplings and the vacuum expe...
متن کاملOrigin and Mechanisms of Cp Violation
It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for giving mass to the bosons and the fermions, but also a mechanism for generating CP-phase of the bosons and the fermions. A two-Higgs doublet model with Vacuum CP Violation and Approximate Global U(1) Family Symmetries (AGUFS) is built and may provide one of the simplest and attractive models in und...
متن کاملA Model for the Origin and Mechanisms of Cp Violation
In this talk I will show that the two-Higgs doublet model with vacuum CP violation and approximate global U(1) family symmetries may provide one of the simplest and most attractive models for understanding the origin and mechanisms of CP violation. It is shown that the mechanism of spontaneous symmetry breaking provides not only a mechanism for generating masses of the bosons and fermions, but ...
متن کاملCP violation as a probe of flavor origin in Supersymmetry
We address the question of the relation between supersymmetry breaking and the origin of flavor in the context of CP violating phenomena. We prove that, in the absence of the Cabibbo–Kobayashi–Maskawa phase, a general Minimal Supersymmetric Standard Model with all possible phases in the soft–breaking terms, but no new flavor structure beyond the usual Yukawa matrices, can never give a sizeable ...
متن کاملFuture probes of the origin of CP violation
We review what has been learned about CP violation in the K system. It is natural to hypothesize that the observed CP-violating effects are caused by the Standard Model weak interaction. We describe the stringent future test of this hypothesis via experiments on the B system. Then, we see how new physics beyond the Standard Model could be revealed by this test. 1. What do we already know? Befor...
