全国第十八届重味物理和CP破坏研讨会（HFCPV 2021）

Some fine differences between the twin -flavored unitarity triangles are calculated by means of a generalized Wolfenstein parametrization of the CKM matrix, and a possible way to experimentally establish the uncharted one is briefly discussed. In addition, the four-zero textures of Hermitian quark mass matrices with an up-down parallelism are considered to understand the salient features of quark flavor mixing and CP violation.
