Thermal WIMPs and the Scale of New Physics: Global Fits of Dirac Dark Matter Effective Field Theories
The GAMBIT Collaboration, Peter Athron, Neal Avis Kozar +24
We assess the status of a wide class of WIMP dark matter (DM) models in light of the latest experimental results using the global fitting framework . We perform a…
BBN constraints on the annihilation of MeV-scale dark matter
Paul Frederik Depta, Marco Hufnagel, Kai Schmidt-Hoberg +1
Thermal dark matter at the MeV scale faces stringent bounds from a variety of cosmological probes. Here we perform a detailed evaluation of BBN bounds on the annihilation cross sec…
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…
BBN constraints on MeV-scale dark sectors. Part II. Electromagnetic decays
Marco Hufnagel, Kai Schmidt-Hoberg, Sebastian Wild
Meta-stable dark sector particles decaying into electrons or photons may non-trivially change the Hubble rate, lead to entropy injection into the thermal bath of Standard Model par…
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…
Self-interacting dark matter with a stable vector mediator
Michael Duerr, Kai Schmidt-Hoberg, Sebastian Wild
Light vector mediators can naturally induce velocity-dependent dark matter self-interactions while at the same time allowing for the correct dark matter relic abundance via thermal…
