We propose that the dark matter abundance is set by the decoupling of inelastic scattering instead of annihilations. This coscattering mechanism is generically realized if dark matter scatters against states of comparable mass from the thermal bath. Coscattering points to dark matter that is exponentially lighter than the weak scale and has a suppressed annihilation rate, avoiding stringent constraints from indirect detection. Dark matter upscatters into states whose late decays can lead to observable distortions to the blackbody spectrum of the cosmic microwave background.

Dark Phoenix: dark matter relic from its own decay
A transient post-freeze-out decay window for dark matter, closed by a first-order phase transition that jumps a partner mass, can reduce an overproduced thermal relic to the observed abundance.

Sub-GeV Dark Matter Under Pressure from Direct Detection
PandaX-4T S2-only data yields world-leading sub-GeV dark matter-electron scattering limits for heavy mediators in the 20-200 MeV range, although the result largely overlaps with the collaboration's own just-released analysis.
