Description

In this work, we study the vacuum structure of an extended standard model with \$U(1)\_D\$ symmetry. The potential of the proposed model contains two \$SU(2)\$ scalar doublets and two scalar singlets. We theoretically analyze constraints, such as bounded-from-below, global minimum, and perturbativity up to the Planck scale. The experimental bounds from the Higgs invisible decay are also investigated.
