The Parametric Space of the Two-Higgs-Doublet Model and Sakharov's Baryogenesis Conditions

Understand

The electroweak phase transition in the Two-Higgs-Doublet Model is investigated.

• The Gibbs potential at finite temperature is computed with regard for the one-loop plus ring diagram contributions.
• The strong first-order phase transition satisfying Sakharov's baryogenesis conditions is determined for the values of scalar field masses allowed by experimental data.
• The relation between the model parameters supplying the phase transition to be of the first order is derived.
