Query: Constraints on the dark photon from parity-violation and the W-mass   We present an analysis of the experimental data for parity-violating electron
scattering (PVES) and atomic parity-violation, including the effects of a dark
photon. We derive the favored region of dark photon parameter space, which
provides a good description of the experimental data from the Qweak
Collaboration and the Jefferson Lab PVDIS Collaboration and simultaneously
relieves the tension between the neutron skin thickness determined in the
PREX-II experiment and nuclear-model predictions. In addition, we extract the
parameter region required to explain the latest W-boson mass anomaly. Our
results indicate that a heavy dark photon with mass above the Z boson mass is
favored, while other sources of new physics beyond the Standard Model in
addition to the dark photon would also be expected.
