Defect-Mediated Conversion: Dark Matter from Cosmological Domain-Wall Scattering
João Paulo Pinheiro, Mohamed Younes Sassi
We propose a new mechanism for dark matter genesis, \emph{Defect-Mediated Conversion} (DMC). Cosmological domain walls can host a scalar condensate in their core acting as a mixing…
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…
Electroweak Symmetry Restoration in the N2HDM 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. They can form in several beyond the Stand…
SM fermion scattering off electric charge and CP-violating domain walls in the 2HDM
Mohamed Younes Sassi, Gudrid Moortgat-Pick
In several models of beyond Standard Model physics (BSM) discrete symmetries play an important role. For instance, in order to avoid flavor changing neutral currents (FCNC), a disc…
Domain walls in the Two-Higgs-Doublet Model and their charge and CP-violating interactions with Standard Model fermions
Mohamed Younes Sassi, Gudrid Moortgat-Pick
Discrete symmetries play an important role in several extensions of the Standard Model (SM) of particle physics. For instance, in order to avoid flavor changing neutral currents, a…
The dipole formalism for massive initial-state particles and its application to dark matter calculations
Julia Harz, Michael Klasen, Mohamed Younes Sassi +1
The dark matter abundance plays a crucial role in the determination of the valid parameter space of models both in the case of a discovery of dark matter and in the context of excl…
