Stability and symmetry breaking in the general three-Higgs-doublet model

Understand

Stability, electroweak symmetry breaking, and the stationarity equations of the general three-Higgs-doublet model (3HDM) where all doublets carry the same hypercharge are discussed in detail.

• Employing the bilinear formalism the study of the 3HDM potential turns out to be straightforward.
• For the case that the potential leads to the physically relevant electroweak symmetry breaking we present explicit formulae for the masses of the physical Higgs bosons.
