Reproductive freeze-in of self-interacting dark matter
We present a mechanism for dark matter (DM) production involving a self-interacting sector that at early times is ultrarelativistic but far underpopulated relative to thermal equilibrium (such initial conditions often arise, e.g., from inflaton decay). Although elastic scatterings can establish kine...
