Sažetak
We propose a classically scale invariant extension of the Standard Model where the electroweak symmetry breaking and the mass of the Dark Matter particle come from the common scale. We introduce U(1)X gauge symmetry and X-charged scalar Phi and Majorana fermion N. Scale invariance is broken via Coleman-Weinberg mechanism providing the vacuum expectation value of the scalar Phi. Stability of the dark matter candidate N is guaranteed by a remnant Z2 symmetry. The Higgs boson mass and the mass of the Dark Matter particle have a common origin, the vacuum expectation value of Phi. Dark matter relic abundance is determined by annihilation NN to Phi Phi. We scan the parameter space of the model and find the mass of the dark matter particle in the range from 500 GeV to a few TeV.
