TL;DR

This paper explores unique decay signatures in the Higgs sector arising from an S3 flavor symmetry model, extending previous work to include a comprehensive scalar spectrum and potential new decay channels observable at the LHC.

Contribution

It introduces a complete analysis of the scalar sector in an S3 flavor model, identifying novel decay channels and revisiting potential minimization under current experimental constraints.

Findings

Identification of new decay signatures involving multileptons of different flavors.

Revised scalar spectrum consistent with LHC limits.

Potential discovery channels in rare top decays at the LHC.

Abstract

In an earlier work we analyzed the CP-even scalar sector of an S3 flavor model, where we identified some novel decay signatures of an exotic scalar. In this work we extend our analysis by including the complete set of scalars/pseudoscalars, revisiting the potential minimization conditions in a more general setup, setting the spectrum in conformity with the current LHC limits on the scalar mass, and identifying yet another spectacularly novel decay channel which might be revealed from an intense study of rare top decays at the LHC into modes containing multileptons of different flavors.
