Dark matter bound states made easy
Simone Biondini, Stefan Vogl
A light force carrier can mediate long-range interactions between dark matter particles and facilitate the formation of bound states. Models incorporating these features have attra…
Indirect detection of dark matter with (pseudo)-scalar interactions
Simone Biondini, Julian Bollig, Stefan Vogl
Indirect detection is one of the most powerful methods to search for annihilating dark matter. In this work, we investigate the impact of non-perturbative effects in the indirect d…
Boosting the production of sterile neutrino dark matter with self-interactions
Maria Dias Astros, Stefan Vogl
Sterile neutrinos are well-motivated and simple dark matter (DM) candidates. However, sterile neutrino DM produced through oscillations by the Dodelson-Widrow mechanism is excluded…
Warm dark matter from a gravitational freeze-in in extra dimensions
Arturo de Giorgi, Stefan Vogl
We study the freeze-in of gravitationally interacting dark matter in extra dimensions. Focusing on a minimal dark matter candidate that only interacts with the SM via gravity in a…
Impact of bound states on non-thermal dark matter production
Julian Bollig, Stefan Vogl
We explore the impact of non-perturbative effects, namely Sommerfeld enhancement and bound state formation, on the cosmological production of non-thermal dark matter. For this purp…
Dark matter interacting via a massive spin-2 mediator in warped extra-dimensions
Arturo de Giorgi, Stefan Vogl
We study dark matter interacting via a massive spin-2 mediator. To have a consistent effective theory for the spin-2 particle, we work in a warped extra-dimensional model such that…
