Bounds from Stability and Symmetry Breaking on Parameters in the Two-Higgs-Doublet Potential
Abstract
Description
The most general $SU(2)\times U(1)_Y$-symmetric quartic potential with two Higgs doublets, subject to an only softly broken discrete symmetry $(ϕ_1,ϕ_2)\to(-ϕ_1,ϕ_2)$, is considered. At tree-level, analytic bounds on the parameters are derived that ensure a stable vacuum, breaking $SU(2)\times U(1)_Y$ down to $U(1)_{em}$.
