Abstract：We consider a scale invariant extension of the standard model (SM) with a combined breaking of conformal and electroweak symmetry in a strongly interacting hidden non-abelian sector with vector-like hidden fermions, which have U(1) hyper charge. It is no longer dark hidden sector. The (pseudo) Nambu-Goldstone bosons that arise due to dynamical chiral symmetry breaking are dark matter (DM) candidates. We study DM properties and discuss consistent parameter space.
