| Summary:
Inverse decays are an interesting avenue for producing dark matter in the
early universe. We study in detail various phases of dark matter parameter
space where inverse decays control its abundance, expanding on our work of INDY
dark matter and going beyond. The role of initial conditions and the impact of
departure from kinetic equilibrium are investigated as well. We show how these
inverse decay phases can arise in theories of a kinetically mixed dark photon
and dark Higgs, with promising prospects for detection at upcoming experiments.
