Copositivity criteria, scalar mass eigenstates, and custodial symmetry parameter $Δ ρ$ for the $S_{3} \otimes Z_{2}$ model

Abstract

We present the copositivity criteria for the scalar sector of our $S_{3} \otimes Z_{2}$ model, which ensures that it is bounded from below. We also show the scalar mass eigenstates, and identify the Standard Model Higgs boson among these by imposing that its Yukawa couplings are the same in our model and the Standard Model. The $Δ ρ$ parameter, related to the custodial symmetry, is calculated as well.
