Discrete symmetries employed to explain flavor mixing and mass hierarchies can be associated with an enlarged scalar sector which might lead to exotic Higgs decay modes. In this paper, we explore such a possibility in a scenario with $S_3$ flavor symmetry which requires three scalar SU(2) doublets. The spectrum is fixed by minimizing the scalar potential, and we observe that the symmetry of the model leads to tantalizing Higgs decay modes potentially observable at the CERN Large Hadron Collider (LHC).

The paper
Original abstract
Discrete symmetries employed to explain flavor mixing and mass hierarchies can be associated with an enlarged scalar sector which might lead to exotic Higgs decay modes. In this paper, we explore such a possibility in a scenario with $S_3$ flavor symmetry which requires three scalar SU(2) doublets. The spectrum is fixed by minimizing the scalar potential, and we observe that the symmetry of the model leads to tantalizing Higgs decay modes potentially observable at the CERN Large Hadron Collider (LHC).

Earlier, the signatures of $h^0$ were studied [ref] , but the residual $ℤ_2$ symmetry was not identified and thus the generic behavior of other similar scalars was not realized properly.

The present analysis extends on our previous discussion [ref] in the following crucial points: $i$) determination of the mass spectrum of the neutral scalars/pseudoscalars and the charged scalars following an improved potential minimization technique, $ii$) calculation of their couplings to the gauge bosons and matter fields, and $iii$) identification of a novel channel of a scalar (pseudoscalar) decay within reach of the LHC.

The allowed ranges for the masses can be found by a random scattering in the parameter space where the couplings in the potential are varied within $λ_{1…8}∈[-π,π]$ and the ratio $v_3/v$ is fixed to $0.6$ (this value was chosen in Ref. [ref] for compatibility with the quark masses).

This is in stark contrast to the mixing of $h_1,2,3$ and $h_a,b,c$ given in Ref. [ref] , where the coefficients are complicated functions of the $λ_{1…8}$ parameters of Eq. ([ref]): [equation] where $U_ib$ and $U_ic$ are complicated functions of the $λ_{1…8}$, $v$ and $v_3$.

In the context of 3HDM, various authors have studied the cases with the discrete symmetry being the permutation groups $S_3$ [ref] , or $S_4$ [ref] , as well as $A_4$, the symmetry group of a regular tetrahedron [ref] .

For a three-Higgs-doublet model with $S3$ symmetry novel scalar decays [ref] , the spectrum of the scalar sector and its consequences [ref] , and the high energy behaviour of the potential [ref] have been explored. $A4$ as a flavour symmetry for lepton and quark masses was first considered in [ref] who introduced three scalar doublets transforming as a triplet of the $A4$ group and wrote down the most general potential consistent with the symmetry.
