Directly detecting sub-GeV dark matter with electrons from nuclear scattering
Matthew J. Dolan, Felix Kahlhoefer, Christopher McCabe
Dark matter (DM) particles with mass in the sub-GeV range are an attractive alternative to heavier weakly-interacting massive particles, but direct detection of such light particle…
Revised constraints and Belle II sensitivity for visible and invisible axion-like particles
Matthew J. Dolan, Torben Ferber, Christopher Hearty +2
Light pseudoscalars interacting pre-dominantly with Standard Model gauge bosons (so-called axion-like particles or ALPs) occur frequently in extensions of the Standard Model. In th…
Exploring light mediators with low-threshold direct detection experiments
Felix Kahlhoefer, Suchita Kulkarni, Sebastian Wild
We explore the potential of future cryogenic direct detection experiments to determine the properties of the mediator that communicates the interactions between dark matter and nuc…
Effective description of dark matter self-interactions in small dark matter haloes
Janis Kummer, Felix Kahlhoefer, Kai Schmidt-Hoberg
Self-interacting dark matter may have striking astrophysical signatures, such as observable offsets between galaxies and dark matter in merging galaxy clusters. Numerical N-body si…
Status of the scalar singlet dark matter model
The GAMBIT Collaboration, Peter Athron, Csaba Balázs +24
One of the simplest viable models for dark matter is an additional neutral scalar, stabilised by a symmetry. Using the GAMBIT package and combining results from four…
DarkBit: A GAMBIT module for computing dark matter observables and likelihoods
Torsten Bringmann, Jan Conrad, Jonathan M. Cornell +11
We introduce DarkBit, an advanced software code for computing dark matter constraints on various extensions to the Standard Model of particle physics, comprising both new native co…
Dark matter self-interactions from a general spin-0 mediator
Felix Kahlhoefer, Kai Schmidt-Hoberg, Sebastian Wild
Dark matter particles interacting via the exchange of very light spin-0 mediators can have large self-interaction rates and obtain their relic abundance from thermal freeze-out. At…
Recommendations of the LHC Dark Matter Working Group: Comparing LHC searches for heavy mediators of dark matter production in visible and invisible decay channels
Andreas Albert, Mihailo Backovic, Antonio Boveia +27
Weakly-coupled TeV-scale particles may mediate the interactions between normal matter and dark matter. If so, the LHC would produce dark matter through these mediators, leading to…
Review of LHC Dark Matter Searches
Felix Kahlhoefer
This review discusses both experimental and theoretical aspects of searches for dark matter at the LHC. An overview of the various experimental search channels is given, followed b…
Hunting the dark Higgs
Michael Duerr, Alexander Grohsjean, Felix Kahlhoefer +3
We discuss a novel signature of dark matter production at the LHC resulting from the emission of an additional Higgs boson in the dark sector. The presence of such a dark Higgs bos…
Simplified dark matter models with two Higgs doublets: I. Pseudoscalar mediators
Martin Bauer, Ulrich Haisch, Felix Kahlhoefer
We study a new class of renormalisable simplified models for dark matter searches at the LHC that are based on two Higgs doublet models with an additional pseudoscalar mediator. In…
