Different vacua in two-Higgs-doublet model

Year: 2007

Type: article

Abstract: We discuss the extrema of the two-Higgs-doublet model with different physical properties. We have found necessary and sufficient conditions for realization of the extrema with different properties as the vacuum state of the model. We found explicit equations for extremum energies via parameters of potential if it has explicitly $CP$ conserving form. These equations allow to pick out extremum with lower energy---vacuum state and to look for change of extrema (phase transitions) with the variation of parameters of potential. Our goal is to find a general picture here to apply it for description of the early Universe.
