The paper argues that adding decays to dark matter broadens the dark photon and could relax the CMS exclusion bound on its mixing parameter by one to two orders of magnitude.

abstract
In the context of future electroweak precision measurements at the Future Circular Lepton Collider (FCC-ee), we consider recent proposals aimed at finding signatures of physics beyond the Standard Model. In particular, we focus on recent novel suggestions for very precise direct measurements of $\alpha_{\rm e m}(M_Z^2)$. It is shown that at a level of precision of order $10^{-5}$, the effects of a dark photon may be very significant.

Relaxing constraints on a broad dark photon
The paper argues that adding decays to dark matter broadens the dark photon and could relax the CMS exclusion bound on its mixing parameter by one to two orders of magnitude.
