Fun with non-Abelian dark sectors
Helena Kolešová (University of Stavanger)

Taking axion inflation as an example, we study the evolution of a non-Abelian dark sector coupled to the inflaton for different choices of the confinement scale. Gravitational wave signals could be in principle generated due to a confinement phase transition or fluctuations in the thermal plasma, however, these signals might be strongly suppressed due to the presence of an early matter-dominated era. We also study the reheating of Standard Model fields and explore the possibility of glueball dark matter within this scenario.
