“…[27]. These works also stressed the connection with Coleman-Weinberg realizations of electroweak symmetry breaking alluded to before; for related works in classically scale-invariant models in which fields other than the Higgs have suppressed VEVs, see also [28][29][30][31] (for other possible Coleman-Weinberg constructions, involving nonzero VEVs for other fields other than the Higgs, see for example refs. [32][33][34][35][36][37][38][39][40][41][42]).…”

Scenarios in which the Higgs vacuum arises radiatively and is separated from the origin by a potential barrier at zero temperature are known to be attainable in models with extra singlet scalars, which in the limit of zero barrier height give rise to Coleman-Weinberg realizations of electroweak symmetry breaking. However, this requires large values of Higgs-portal couplings or a large number N of singlets. This is quantified in detail by considering, for varying N , the full two-loop effective potential at zero temperature, as well as finite temperature effects including the dominant two-loop corrections due to the singlets. Despite the large couplings, two-loop effects near the electroweak scale are under control, and actually better behaved in models with larger couplings yet fewer singlets. Strong first-order phase transitions are guaranteed even in the Coleman-Weinberg scenarios. Cubic Higgs couplings and Higgs associated-production cross sections exhibit deviations from the Standard Model predictions which could be probed at a linear collider.

“…It should be noted that allowing for different sectors of scalars with different strength of their Higgs-portal couplings allows to achieve both electroweak-symmetry breaking à la Coleman-Weinberg and dark-matter candidates with the correct relic abundance; see for example ref. [31].…”

“…Furthermore, there is no dark matter (DM) candidate in the SM. Phenomenologically successful models which employ conformal electro-weak symmetry breaking require therefore some extension and a number of them predict also interesting DM candidates [11,18,23,30,31,[36][37][38][39].…”
