Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +1
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…
Matter-antimatter asymmetry and dark matter stability from baryon number conservation
Mar Císcar-Monsalvatje, Alejandro Ibarra, Jérôme Vandecasteele
There is currently no evidence for a baryon asymmetry in our Universe. Instead, cosmological observations have only demonstrated the existence of a quark-antiquark asymmetry, which…
Condensed dark matter with a Yukawa interaction
Raghuveer Garani, Michel H. G. Tytgat, Jérôme Vandecasteele
We explore the possible phases of a condensed dark matter (DM) candidate taken to be in the form of a fermion with a Yukawa coupling to a scalar particle, at zero temperature but a…
Strong dynamics and dark matter: investigating a minimal setup
Benjamin Fuks, Federica Giacchino, Laura Lopez-Honorez +2
We discuss the phenomenology of a dark matter scenario in which we extend the Standard Model by a real scalar particle and a vector-like heavy quark. Such a model can be seen as a…
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…
Radiative corrections to vectorlike portal dark matter
Stefano Colucci, Federica Giacchino, Michel H. G. Tytgat +1
A massive real scalar dark matter particle can couple to Standard Model leptons or quarks through a vector-like fermionic mediator , a scenario known as the Vector-like port…
Top-philic Vector-Like Portal to Scalar Dark Matter
Stefano Colucci, Benjamin Fuks, Federica Giacchino +3
We investigate the phenomenology of scalar singlet dark matter candidates that couple dominantly to the Standard Model via a Yukawa interaction with the top quark and a colored vec…
