Why it is here

A likelihood-based dark-photon fit whose viability depends on depleting the long-lived excited state.

Machine-assisted summary

The authors jointly scan the LZ energy likelihood and relic density for endothermic dark matter with a light kinetically mixed dark photon, finding TeV masses and few-hundred-keV splittings while highlighting late-time excited-state constraints.
