How heavy can dark matter be? Constraining colourful unitarity with SARAH

We describe the automation of the calculation of perturbative unitarity constraints including scalars that have colour charges, and its release in SARAH4.14.4. We apply this, along with vacuum stability constraints, to a simple dark matter model with colourful mediators and interesting decays, and s...

Zusammenfassung:	We describe the automation of the calculation of perturbative unitarity constraints including scalars that have colour charges, and its release in SARAH4.14.4. We apply this, along with vacuum stability constraints, to a simple dark matter model with colourful mediators and interesting decays, and show how it leads to a bound on a thermal relic dark matter mass well below the classic Griest-Kamionkowski limit.
