| Abstract: |
We consider a classically scale invariant extension of the standard model, in which the scale invariance is broken by dynamical chiral symmetry breaking in a QCD-like hidden sector. Because of the unbroken SU(3) flavor symmetry, the quasi Nambu-Goldstone bosons are stable so that they can become dark matter particles. We study their properties with the Nambu-Jona-Lasinio method and also discuss the phase transition in the dark sector as well as in the electroweak sector. |
