The symmetry breaking is performed by a two-doublet Higgs sector supplemented by an extra gauge singlet scalar, realizing an accidental global $U(1)$ symmetry. Its spontaneous breaking at the few TeV scale leads to a physical Nambu-Goldstone boson - the $Diracon$, denoted $\\mathcal{D}$ - which is restricted by astrophysics and induces invisible Higgs decays $h\\to \\mathcal{D} \\mathcal {D}$.
