Abstract
The recent accurate determination of the CKM parameters including the maximal CP phase Ï2 enables us to write down the up-type and down-type quark mass matrices to a high degree of accuracy. The lightest element (u¯u element) of the quark mass texture (not the mass eigenvalue) has a power λ6 where λ=sinθC. The CP phase of 2Ï divided by an integer hints a discrete symmetry. Since λ6 is the highest power of λ among the quark mass matrix elements, we present as an example a possibility that the maximal CP phase Ï2 is obtainable from a supersymmetric Z12 discrete symmetry model.
