The kinetic mixing (KM) portal is a popular mechanism that allows light dark matter (DM) in the mass range below $\ensuremath{\sim}1\text{ }\text{ }\mathrm{GeV}$ to achieve the observed relic density by thermal means and can be effectively described by only a few parameters, e.g., $\ensuremath{\epsilon}$, the strength of this KM.
