چکیده
|
We discuss a simple model of thermal relic dark matter whose mass can be much larger than the so-called unitarity limit on the mass of point-like particle dark matter. the model consists of new strong dynamics with one flavor of fermions in the fundamental representation which is much heavier than the dynamical scale of the new strong dynamics. dark matter is identified with the lightest baryonic hadron of the new dynamics. the baryonic hadrons annihilate into the mesonic hadrons of the new strong dynamics when they have large radii. resultantly, thermal relic dark matter with a mass in the pev range is possible.
