New parameterization and analysis for E6 inspired 331 model

TL;DR

This paper introduces a new parameterization for an $E_6$ inspired extension of the Standard Model, accurately predicting quark mixing angles and masses with minimal parameters, supported by detailed numerical analysis.

Contribution

The paper proposes a novel parameterization for the $E_6$ inspired 331 model that effectively predicts quark mixing and masses with fewer input parameters than previous models.

Findings

Predicted all CKM mixing angles within 1-3 standard deviations.

Achieved a best fit with $ ext{chi}^2 oughly 0.7$ and $orall ext{sigma}<0.6$.

Demonstrated advantages of the new parameterization over existing approaches.

Abstract

We present a new parameterization for $E_6$ inspired $SU(3)_C\times SU(3)_L\times U(1)_X$ extension of the Standard Model. New setup predicts all Cabibbo-Kobayashi-Maskawa mixing angles and quark masses, 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 $\chi^2\approx 0.7$ with $\forall\sigma<0.6$. Advantages of the new parameterization and future prospects are discussed as well.
