We construct a minimal viable extension of the standard model (SM) with classical scale symmetry. Its scalar sector contains a complex singlet in addition to the SM Higgs doublet. The scale-invariant and CP- symmetric Higgs potential generates radiative electroweak symmetry breaking à la Coleman–Weinberg. Besides the 125 GeV SM-like Higgs particle, it predicts an additional CP-even Higgs and a CP-odd scalar singlet (providing the dark matter candidate) at weak scale. We systematically analyze theoretical and experimental constraints and demonstrate the viable parameter space.
