Abstract

We present a new parameterization for SU(3)C × SU(3)L × U(1)X extension of the Standard Model, which is inspired by E6 symmetry. The new setup predicts all Cabibbo-Kobayashi-Maskawa mixing angles and quark masses, a total of nine observable variables, within 1–3 standard deviations of the experimental values with a minimum number of input parameters. A detailed numerical analysis and correlations between input parameters and predicted quantities are presented. The best global fit benchmark point corresponds to χ 2 ≈ 0.7 with ∀σ < 0.6. The advantages of the new parameterization and future prospects are discussed as well.
