TITLE
A new approach to the Dark Matter-Baryon coincidence problem
ABSTRACT
The comparable abundances of dark matter and baryons, known as the Dark Matter-Baryon coincidence, call for an explanation that relates the dark sector to the QCD sector. In models of Asymmetric Dark Matter, the number densities of both sectors are naturally similar. However, a complete solution should also include a mechanism to ensure comparable masses. In this talk, I will present a new mechanism where the dark matter mass also originates from the QCD vacuum, naturally placing it at the GeV scale, comparable to baryon masses. The UV completion and relevant phenomenology will also be discussed.
