  In the standard model (SM) the condition that the Higgs mass parameter
vanishes is stable under radiative corrections and yields a theory that can be
renormalized using dimensional regularization. Thus, this model allows to
predict the Higgs boson mass. However, it is phenomenologically ruled out in
its minimal version. Here, we present a phenomenologically viable, minimal
extension which only includes an additional SM singlet and a U(1)$_X$ gauge
symmetry.
