Description
We discuss simple scenarios where quark flavor-violating couplings generate the observed dark
matter abundance through freeze-in of an axion-like particle with mass in the few keV range. We show that these
scenarios are constrained by supernovae, structure formation and collider bounds and can be almost entirely probed by future X-ray telescopes.
