| Title: | The Higgs vacuum uplifted: revisiting the electroweak phase transition with a second Higgs doublet |
| Authors: | Gláuber Carvalho Dorsch Stephan J. Huber Ken Mimasu Jose Miguel No Redondo |
| Abstract: | The existence of a second Higgs doublet in Nature could lead to a cosmological first order electroweak phase transition and explain the origin of the matter-antimatter asymmetry in the Universe. We explore the parameter space of such a two-Higgs-doublet- model and show that a first order electroweak phase transition strongly correlates with a significant uplifting of the Higgs vacuum w.r.t. its Standard Model value. We then obtain the spectrum and properties of the new scalars H0, A0 and H± that signal such a phase transition, showing that the decay A0 H0Z at the LHC and a sizable deviation in the Higgs self-coupling λhhh from its SM value are sensitive indicators of a strongly first order electroweak phase transition in the 2HDM. |
