Systematic analysis of 3HDM symmetries
A. KunÄinas, P. Osland, M. N. Rebelo
Symmetries play a crucial role in shaping the structure and predictions of multi-Higgs-doublet models. In three-Higgs-doublet models considerable effort has been put into classifyi…
Dark Matter in Multi-Singlet Extensions of the Standard Model
Maria Gonçalves, Margarete Mühlleitner, Rui Santos +1
We study the simplest extensions of the Standard Model (SM) that provide Dark Matter (DM) candidates, built with the addition of real singlets and new symmetries. I…
Towards a Unified Framework for Pseudo-Nambu-Goldstone Dark Matter and Electroweak Baryogenesis
Thomas Biekötter, Pedro Gabriel, Milada Margarete Mühlleitner +1
We propose the complex singlet-extended 2-Higgs-Doublet Model (cS2HDM), a spin-0 Dark Matter (DM) model with a Higgs sector consisting of two Higgs doublets and a complex singlet,…
Perturbative unitarity for models with singlet and doublet scalars
Carolina T. Lopes, André Milagre, João P. Silva
We provide a complete description of perturbative unitarity bounds on the gauge-scalar sectors of models with extra doublet, neutral singlet, and charged singlet scalars. S…
Goofy transformations and the hierarchy problem
Andreas Trautner
Goofy transformations of the Standard Model (SM) Higgs field generally prohibit its bare mass term. This opens up an entirely new class of solutions to the electroweak (EW) hierarc…
RelExt: A New Dark Matter Tool for the Exploration of Dark Matter Models
Rodrigo Capucha, Karim Elyaouti, Milada Margarete Mühlleitner +2
We present the C++ program RelExt for Standard Model (SM) extensions that feature a Dark Matter (DM) candidate. The tool allows to efficiently scan the parameter spaces of these mo…
