abstract
We revisit the exclusion constraints on the parameters of a narrow dark photon set by direct experimental searches. We investigate how a dark photon with a larger decay width impacts these limits, in particular, in the case where the dark photon also decays into light dark matter. As an example, taking the upper limits on the mixing parameter, $\epsilon$, reported by the CMS collaboration, we find that they could be significantly relaxed. Indeed, even a very modest coupling of the dark photon to dark matter can lead to an increase in the bound on the mixing parameter by an order of magnitude.

Relaxed constraints for dark matter with axial coupling to a dark photon
Axial coupling of Dirac dark matter to a kinetically-mixed dark photon suppresses the standard direct-detection signal and opens large allowed regions in the WIMP parameter space.

Evidence for and implications of a dark photon
A global QCD fit to deep-inelastic scattering prefers a dark photon with mass 4 to 6 GeV and mixing 0.06 to 0.12, claimed as a 6.5 sigma hint, though direct searches exclude these parameters unless extra dark matter c...
