Seminarium Kosmologia i Fizyka Cząstek

We study the Coleman-Weinberg mechanism of radiative symmetry breaking in a classically scale invariant modification of the Standard Model extended by two, singlet under SM gauge symmetries, scalar fields where one of them plays a role of a stable dark matter particle. The spontaneous symmetry breaking is realized in the Gildener-Weinberg framework. We derive explicit expressions for the vevs and scalar sector masses corrections with respect to the leading formulas and apply the expressions in phenomenological analysis.
