  We investigate a perturbative extension of the Standard Model featuring
elementary pseudo-Goldstone Higgs and dark matter particles. These are two of
the five Goldstone bosons parametrising the SU(4)/Sp(4) coset space. They
acquire masses, and therefore become pseudo-Goldstone bosons, due to the
embedding of the Yukawa and the electroweak gauge interactions that do not
preserve the full SU(4) symmetry. At the one-loop order the top corrections
dominate and align the vacuum in the direction where the Higgs is mostly a
pseudo-Goldstone boson. Because of the perturbative and elementary nature of
the theory, the quantum corrections are precisely calculable. The remaining
pseudo-Goldstone boson is identified with the dark matter candidate because it
is neutral with respect to the Standard Model and stable. By a direct
comparison with the Large Hadron Collider experiments, the model is found to be
phenomenologically viable. Furthermore the dark matter particle leads to the
observed thermal relic density while respecting the most stringent current
experimental constraints.
