Composite 2HDM with singlets: a viable dark matter scenario.

We study the non-minimal composite Higgs modelwith global symmetry$\SO(7)$ broken to $\ SO(5)\times \SO(2)$. The model results in a composite Two-Higgs doublet model(2HDM) equipped with two extra singlets, the lightest of which can be a viable dark mattercandidate. The model is able to reproduce the correct dark matterrelic density both via the usual thermal freeze-out and through late time decay of the heavier singlet. In the case of thermal freeze-out, it is possible to evade current experimental constraints even with the minimum fine tuningallowed by electroweak precision tests.
