On the challenges of searching for GeV-scale long-lived particles at the LHC
Elias Bernreuther, Juliana Carrasco Mejia, Felix Kahlhoefer +2
Many models of dark matter predict long-lived particles (LLPs) that can give rise to striking signatures at the LHC. Existing searches for displaced vertices are however tailored t…
Probing Higgs-portal dark matter with vector-boson fusion
Jan Heisig, Michael Krämer, Eric Madge +1
We constrain the Higgs-portal model employing the vector-boson fusion channel at the LHC. In particular, we include the phenomenologically interesting parameter region near the Hig…
Completing the scalar and fermionic Universal One-Loop Effective Action
Michael Krämer, Benjamin Summ, Alexander Voigt
We extend the known Universal One-Loop Effective Action (UOLEA) by all operators which involve scalars and fermions, not including contributions arising from open covariant derivat…
Strongly interacting dark sectors in the early Universe and at the LHC through a simplified portal
Elias Bernreuther, Felix Kahlhoefer, Michael Krämer +1
We study the cosmology and LHC phenomenology of a consistent strongly interacting dark sector coupled to Standard Model particles through a generic vector mediator. We lay out the…
