Abstract
The weak mixing angles, the masses of quarks and leptons are free parameters of the standard electroweak model. In spite of the success of the model, no deeper clue has been provided so far towards the yet unknown dynamics, which is responsible for the mass spectra and the mixing parameters. The Cabibbo-Kobayashi-Maskawa (CKM) matrix incorporates three mixing angles and one CP-violating phase. Various parametrizations of such a matrix have been proposed during the last thirty years or so. The problem of quark-mass matrices has eluded a unique solution, but several useful forms have been proposed in literature. In this note, an exponential parametrization of the Cabibbo-Kobayashi-Maskawa matrix, which allows a straightforward derivation of the symmetric quark-mass matrices, is proposed.
