Freeze-in of anapole and charge-radius inelastic dark matter: X-ray probes of a decoupled vector portal
- Published

- arXiv:2609.34230
Why it is here
The same excited-state population connects an exothermic direct-detection signal to X-ray limits and the reheating history.
Machine-assisted summary
Freeze-in through transition anapole or charge-radius operators leaves a long-lived excited state whose exothermic down-scattering can explain the LZ recoil, while its three-photon decay is tested by NuSTAR and INTEGRAL/SPI.
