Resonant or asymmetric: The status of sub-GeV dark matter
Sowmiya Balan, Csaba Balázs, Torsten Bringmann +9
Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the strong constraints on heavier DM candidates but at the same time face a multitude of new constr…

Relaxing Limits from Big Bang Nucleosynthesis on Heavy Neutral Leptons with Axion-like Particles
Frank F. Deppisch, Tomás E. Gonzalo, Chayan Majumdar +1
Heavy neutral leptons (HNLs) are constrained by requirements of Big Bang Nucleosynthesis (BBN) as their decays significantly impact the formation of the primordial elements. We pro…

Global fit to the 2HDM with generic sources of flavour violation using \textsf{GAMBIT}
Peter Athron, Andreas Crivellin, Tomás E. Gonzalo +2
We perform a global statistical analysis of the two-Higgs-doublet model with generic sources of flavour violation using \textsf{GAMBIT}. This is particularly interesting in light o…
