Producing and constraining self-interacting hidden sector dark matter
Laurent Vanderheyden
In this thesis, we start by reviewing all constraints applying on self-interacting DM with a light mediator considering well-known Higgs portal and Kinetic Mixing portal models as…
Dark matter from dark photons
Laurent Vanderheyden
In this talk, I explained how the observed dark matter (DM) relic abundance can be accounted for in models composed of three sectors (the DM, the Standard Model (SM) and a light me…
The domain of thermal dark matter candidates
Rupert Coy, Thomas Hambye, Michel H. G. Tytgat +1
We consider, in general terms, the possible parameter space of thermal dark matter candidates. We assume that the dark matter particle is fundamental and was in thermal equilibrium…
Dark matter as a heavy thermal hot relic
Thomas Hambye, Matteo Lucca, Laurent Vanderheyden
If, during the early Universe epoch, the dark matter particle thermalizes in a hidden sector which does not thermalize with the Standard Model thermal bath, its relativistic therma…
Dark matter from dark photons: a taxonomy of dark matter production
Thomas Hambye, Michel H. G. Tytgat, Jérôme Vandecasteele +1
We analyse how dark matter (DM) can be produced in the early universe, working in the framework of a hidden sector charged under a U(1)' gauge symmetry and interacting with the Sta…
Direct Detection is testing Freeze-in
Thomas Hambye, Michel H. G. Tytgat, Jérôme Vandecasteele +1
Dark Matter (DM) may belong to a hidden sector that is only feebly interacting with the Standard Model (SM) and may have never been in thermal equilibrium in the Early Universe. In…
