Abstract

A model of the 3 × 3 Cabibbo-Kobayashi-Maskawa matrix, V, is presented in which the parameters are the eigenvalues and the components of its eigenvectors. In this model, the small departure of the experimentally determined V from being moduli symmetric (i.e. |Vij|=|Vji|) is controlled by the small difference between two of the eigenvalues. In case any two eigenvalues are equal, one obtains a moduli symmetric V depending on only three parameters. Our model gives very good fits to the available data including CP-violation. Our value of sin 2ߘ0.7 and other parameters associated with the ''unitarity triangle'' V11V∗13+V21V∗ 23V31V ∗33 = 0 are in good agreement with data and other analyses.
