Comments on the Characteristic Measurables of the Quark Mixing Matrix
Abstract
Description
Within the standard electroweak model we point out that the $3\times 3$ matrix of quark mixing is characterized by three universal (rephasing-invariant) quantities: one of them for $CP$ violation and the other two for off-diagonal asymmetries. Unitarity of the quark mixing matrix can in principle be tested through a variety of measurements which are irrelevant to the existence of $CP$-violating effects.
Two new paragraphs, together with three relevant references, are added. We find an interesting hierarchical relation among the nine elements of the CKM matrix; and estimate the nine different angles of the six unitarity triangles
