Unitarity and Bound-State Formation Constraints on Dark Matter


  • Dr. William SHEPHERD

Primary authors

Abstract content

I present rigorous calculations of the constraints that perturbativity and unitarity apply to dark matter in the well-known portal scenarios. These provide the most stringent upper limit on dark matter mass in the thermal cosmology. I will also discuss the physics of dark matter bound states that can become important when the interactions of dark matter become so strong.
