Higgs-Pair Production via Gluon Fusion: Top-Yukawa- and light-quark-induced electroweak Corrections
Arunima Bhattacharya, Francisco Campanario, Sauro Carlotti +5
Gluon fusion, , is the dominant Higgs-pair production process at the Large Hadron Collider (LHC) and provides the first direct access to the trilinear Higgs self-interact…
Phenomenology of a Kinetic Higgs Portal
Anisha, Lisa Biermann, Christoph Englert +1
We explore the phenomenological consequences of non-minimal hidden sector interactions on observable correlations in the Higgs sector, mediated through the -symmetric…
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,…
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…
Freeze-in as a Complementary Process to Freeze-Out
Rodrigo Capucha, Karim Elyaouti, Margarete Mühlleitner +2
There are many extensions of the Standard Model with a dark matter (DM) candidate obtained via the freeze-out mechanism. It can happen that after all experimental and theoretical c…
Higgs Mass Predictions in the CP-Violating High-Scale NMSSM
Christoph Borschensky, Thi Nhung Dao, Martin Gabelmann +2
In a supersymmetric theory, large mass hierarchies can lead to large uncertainties in fixed-order calculations of the Standard Model (SM)-like Higgs mass. A reliable prediction is…
