Dynamic freeze-in: impact of thermal masses and cosmological phase transitions on dark matter production
Abstract The cosmological abundance of dark matter can be significantly influenced by the temperature dependence of particle masses and vacuum expectation values. We illustrate this point in three simple freeze-in models. The first one, which we call kinematically induced freeze-in, is based on the...
