Why it is here

One exothermic pseudo-Dirac benchmark connects the LZ candidate to the Galactic Center excess while requiring an excited state that survives to the present halo.

Machine-assisted summary

The authors propose 20--100 GeV pseudo-Dirac dark matter coupled through a hadrophilic baryon-number vector, with a cosmologically long-lived excited state whose roughly MeV downscattering can fit the xenon recoil in the same thermal parameter space as the Galactic Center gamma-ray excess.
