Existence and properties of the electroweak phase transition in the early universe depend strongly on the mass of the Higgs scalar MH. There is presumably no true symmetry restoration at high temperature. Nevertheless, a first order phase transition occurs in the standard model for M

CP violation of the SM is insufficient to explain the baryon asymmetry in the universe and therefore an additional source of CP violation is needed. Here the extension of the SM by a neutral complex scalar singlet with a nonzero vacuum expectation value (cSMCS) plus a heavy vector quark pair is considered. This model offers the spontaneous CP viola...
We investigate feasibility of efficient baryogenesis at the electroweak scale
within the effective field theory framework based on a non-linear realisation
of the electroweak gauge symmetry. In this framework the LHC Higgs boson is
described by a singlet scalar field, which, therefore, admits new interactions.
Assuming that Higgs couplings with the...
Electroweak baryogenesis is an attractive scenario for explaining the baryon asymmetry of the
universe. However, it does not work within the standard model due to two reasons: (1) the strength of CP violation from the Kobayashi-Maskawa mechanism with three generations is too small; (2) the electroweak phase transition is not first order for the exp...
