Probing non-thermal light DM with structure formation and
Sven Baumholzer, Pedro Schwaller
In many models of dark matter (DM), several production mechanisms contribute to its final abundance, often leading to a non-thermal momentum distribution. This makes it more diffic…
Structure Formation Limits on Axion-Like Dark Matter
Sven Baumholzer, Vedran Brdar, Enrico Morgante
We derive structure formation limits on dark matter (DM) composed of keV-scale axion-like particles (ALPs), produced via freeze-in through the interactions with photons and Standar…
Shining Light on the Scotogenic Model: Interplay of Colliders and Cosmology
Sven Baumholzer, Vedran Brdar, Pedro Schwaller +1
In the framework of the scotogenic model, which features radiative generation of neutrino masses, we explore light dark matter scenario. Throughout the paper we chiefly focus on ke…
The New MSM : Radiative Neutrino Masses, keV-Scale Dark Matter and Viable Leptogenesis with sub-TeV New Physics
Sven Baumholzer, Vedran Brdar, Pedro Schwaller
We study the scenario in which the Standard model is augmented by three generations of right-handed neutrinos and a scalar doublet. The newly introduced fields share an odd charge…
