Description
The comparable abundances of dark matter and baryons, known as the dark matter–baryon coincidence, call for an explanation that connects the dark sector to the QCD sector. In this talk, I will present a detailed analysis showing why this coincidence is nontrivial and points toward a strongly coupled dark sector with $\mathcal{O}(1)$-GeV asymmetric dark baryons as dark matter. Based on this insight, we examine the interplay between direct detection experiments and searches for feebly interacting particles, highlighting how these complementary probes can test and distinguish different solutions to the coincidence problem.
