Model-independent bounds on light pseudoscalars from rare B-meson decays
Babette Döbrich, Fatih Ertas, Felix Kahlhoefer +1
New light pseudoscalars, such as axion-like particles, appear in many well-motivated extensions of the Standard Model and provide an exciting target for present and future experime…
LHC Dark Matter Working Group: Next-generation spin-0 dark matter models
Tomohiro Abe, Yoav Afik, Andreas Albert +50
Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS Collaborations to interpret searches for missing transverse energy (). The coher…
Axion global fits with Peccei-Quinn symmetry breaking before inflation using GAMBIT
Sebastian Hoof, Felix Kahlhoefer, Pat Scott +2
We present global fits of cosmologically stable axion-like particle and QCD axion models in the mass range 0.1 neV to 10 eV. We focus on the case where the Peccei-Quinn symmetry is…
Freeze-in production of decaying dark matter in five steps
Saniya Heeba, Felix Kahlhoefer, Patrick Stöcker
We study the cosmological evolution and phenomenological properties of scalar bosons in the keV to MeV range that have a tiny mixing with the Standard Model Higgs boson. The mixing…
The Belle II Physics Book
E. Kou, P. Urquijo, W. Altmannshofer +524
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB collider. Belle II collected its first collisions in 2018, and is ex…
Global analyses of Higgs portal singlet dark matter models using GAMBIT
The GAMBIT Collaboration, Peter Athron, Csaba Balázs +15
We present global analyses of effective Higgs portal dark matter models in the frequentist and Bayesian statistical frameworks. Complementing earlier studies of the scalar Higgs po…
Impact of vacuum stability, perturbativity and XENON1T on global fits of and scalar singlet dark matter
Peter Athron, Jonathan M. Cornell, Felix Kahlhoefer +3
Scalar singlet dark matter is one of the simplest and most predictive realisations of the WIMP (weakly-interacting massive particle) idea. Although the model is constrained from al…
Materials Informatics for Dark Matter Detection
R. Matthias Geilhufe, Bart Olsthoorn, Alfredo Ferella +4
Dark Matter particles are commonly assumed to be weakly interacting massive particles (WIMPs) with a mass in the GeV to TeV range. However, recent interest has shifted towards ligh…
Converting non-relativistic dark matter to radiation
Torsten Bringmann, Felix Kahlhoefer, Kai Schmidt-Hoberg +1
Dark matter in the cosmological concordance model is parameterised by a single number, describing the covariantly conserved energy density of a non-relativistic fluid. Here we test…
Model-independent comparison of annual modulation and total rate with direct detection experiments
Felix Kahlhoefer, Florian Reindl, Karoline Schäffner +2
The relative sensitivity of different direct detection experiments depends sensitively on the astrophysical distribution and particle physics nature of dark matter, prohibiting a m…
On the LHC sensitivity for non-thermalised hidden sectors
Felix Kahlhoefer
We show under rather general assumptions that hidden sectors that never reach thermal equilibrium in the early Universe are also inaccessible for the LHC. In other words, any parti…
