Abstract

We propose a model based on the SU(3)CSU(3)LU(1)XSU(3)_{C}\otimes SU(3)_{L}\otimes U(1)_{X} gauge symmetry with an extra S3Z2Z4Z12S_{3}\otimes Z_{2}\otimes Z_{4}\otimes Z_{12} discrete group, which successfully accounts for the SM quark mass and mixing pattern. The observed hierarchy of the SM quark masses and quark mixing matrix elements arises from the Z4Z_{4} and Z12Z_{12} symmetries, which are broken at very high scale by the SU(3)LSU(3)_{L} scalar singlets (σ\sigma,ζ\zeta) and τ\tau , charged under these symmetries, respectively. The Cabbibo mixing arises from the down type quark sector whereas the up quark sector generates the remaining quark mixing angles. The obtained magnitudes of the CKM matrix elements, the CP violating phase and the Jarlskog invariant are in agreement with the experimental data.
