Summary
We point out that the structure of the 3×3 quark mixing matrixV is characterized by its two off-diagonal asymmetries: one about theV
11–V
22–V
33 axis (
) and the other about theV
13−V
22−V
31 axis (
). By use of current experimental data, we obtain
∼10−5−10−4 and
⩾400
. We find a definite hierarchy for the magnitudes of quark mixings: |V
33|>|V
11|>|V
22|≫|V
12|>|V
21|≫≫|V
23|>|V
32|≫|V
31|>|V
13|>0. The useful relations between the off-diagonal asymmetries
and the unitarity triangles ofV are also explored.
