Pion dark matter in a θ vacuum: a thermal relic with sharp velocity-dependent self-interactions
Abstract As recently proposed, a non-vanishing topological angle may play a central role in QCD-like theories of dark matter (DM). In this work, we introduce a dark photon portal to the Standard Model in order to establish thermal equilibrium in the early Universe, and discuss the ensuing phenomenol...
