On the Geometry Origin of Weak CP Phase

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 $\rho$ and $\eta$ are given by present data and the postulation itself. Especially, we predict $0.0076 \leq |V_{td}| \leq 0.0093, 74.9^o \leq \gamma \leq 75.7^o$ when the corresponding inputs are at the $90$. 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.
