Constraints on Light Dark Matter from Core-Collapse Supernovae
We show that light ($\ensuremath{\simeq}1--30\text{ }\text{ }\mathrm{MeV}$) dark matter particles can play a significant role in core-collapse supernovae, if they have relatively large annihilation and scattering cross sections, as compared to neutrinos. We find that if such particles are lighter than $\ensuremath{\simeq}10\text{ }\text{ }\mathrm{MeV}$ and reproduce the observed dark matter …
