چکیده

In this work, the postulation that weak CP phase originates in a certain geometry, is further discussed. Some intrinsic and strict constraints on the mixing angles, weak CP phase, and the Wolfenstein’s parameters ρ and η are given by present data and the postulation itself. Especially, we predict 0.0076 ≤ |Vtd| ≤ 0.0093, 74.9 ≤ γ ≤ 75.7 when the corresponding inputs are at the 90% C. L.. The comparison of the predictions to the relevant experimental and theoretical results is listed. All the predictions coincide with the present experimental results and theoretical analysis very well. PACS number(s): 11.30.Er, 12.10.Ck, 13.25.+m Quark mixing and CP violation [1, 2, 3, 4, 5, 6, 7] is one of the most interesting and important problem in particle physics. Up to now, the origin of CP violation is not clear to us. In the standard model, CP violation originates from a phase which presents in the CKM matrix [8, 9]. Mathematically, (N−1)(N−2) 2 phases are permitted to present in N by N unitarity matrix in addition to N(N−1) 2 Euler angles. However, physics is always in favour of more concise theory. In the previous work [10], we have postulated that, the weak CP phase originates in a certain geometry. Here, we discuss further this issue. The central purpose is to make some predictions which can be tested by more precise data in B-factory in following few years. To make this paper selfcontained, we begin with describing our postulation firstly. 1. The Postulation A. CKM matrix in KM parametrization and SO(3) rotation There are many parametrization of the CKM matrix, such as the standard one advocated by the Particle Data Group [11, 12] and those given by Wolfenstein [13] etc. However, the original parametrization chosed by Kobayashi and Maskawa is more helpful to our understanding the problem, it is [9]

Cabibbo-Kobayashi-Maskawa Matrix Unitarity Triangle and Geometry Origin of the Weak CP Phase

In this work, the postulation that weak CP phase originates in a certain geometry, is further discussed. According to this postulation, the weak CP phase is determined by three mixing angles. So, if we can determine experimentally three elements of the Cabibbo-KobayashiMaskawa (CKM) matrix, we can then determine the whole CKM matrix and correspondingly, the unitarity triangle. We find that the ...

We further investigate the probability that, weak CP phase originates in a certain geometry. We find that our postulation on weak CP Phase gives strict constraints on angle γ in unitarity triangle DB and the element Vtd in Cabibbo-Kobayashi-Maskawa (CKM) matrix. The predicted |Vtd| is about 0.0086 and γ about 75.3 0 with the very narrow window respectively. These two parameters can be used to t...

The relation between CP-violation phase angle and the other three mixing angles in Cabibbo-Kobayashi-Maskawa matrix is postulated. This relation has a very definite geometry meaning. The numerical result coincides surprisingly with that extracting from the experiments. It can be further put to the more precise tests in the future.

Strong Λ π Phase Shifts for CP Violation in Weak Ξ → Λ π Decay ⋆

Strong interaction Λπ phase shifts relevant for the weak nonleptonic decay Ξ → Λπ are calculated using baryon chiral perturbation theory. We find in leading order that the S-wave phase shift vanishes and the J = 1 2 P-wave phase shift is −1.7o. The small phase shifts imply that CP violation in this decay will be difficult to observe. Our results follow from chiral SU(2)L × SU(2)R symmetry. ⋆ Wo...

New Constraint on Weak CP Phase Rephasing Invariant and Maximal CP Violation

By using the relation between CP-violation phase and the mixing angles in CabibboKobayashi-Maskawa matrix postulated by us before, the rephasing invariant is recalculated. Furthermore, the problem about maximal CP violation is discussed. We find that the maximal value of Jarlskog’s invariant is about 0.038. And it presents at α ≃ 71.00, β ≃ 90.20 and γ ≃ 18.80 in triangle db. PACS number(s): 11...
