Vacuum Instability and False Vacuum Decay Induced by Domain Walls in the N2HDM
Mohamed Younes Sassi, Gudrid Moortgat-Pick
The Next-to-Two-Higgs-Doublet model (N2HDM) has a rich vacuum structure where multiple electroweak (EW) breaking minima, as well as CP and electric-charge breaking minima, can coex…

Electroweak Symmetry Restoration in Extended Higgs Sectors via Domain Walls
Mohamed Younes Sassi, Gudrid Moortgat-Pick
Domain walls are a type of topological defects that can arise in the early universe after the spontaneous breaking of a discrete symmetry. This occurs in several beyond Standard Mo…
