The strange physics of dark baryons

The origin of dark matter and the matter-antimatter asymmetry of the Universe may be explained by the existence of GeV-scale dark sector particles carrying baryon number. The interactions of such dark baryons with first-generation quarks are known to have implications for collider experiments, neutron stars, and the lifetime of the neutron. After reviewing these topics, I will focus on the phenomenology of dark baryon interactions with strange quarks. This includes their impact on the decay of exotic hadrons, core-collapse supernova explosions, and new physics searches at the LHC and flavour physics experiments.
