Non-thermal Dark Matter from Modified Early Matter Domination

26 Dec 2018 Allahverdi Rouzbeh Osiński Jacek K.

Thermal freeze-out or freeze-in during a period of early matter domination can give rise to the correct dark matter abundance for $\langle \sigma_{\rm ann} v \rangle_{\rm f} < 3 \times 10^{-26}$ cm$^3$ s$^{-1}$. In the standard scenario, a single field that behaves like matter drives the early matter dominated era... (read more)
