We perform the first global QCD analysis of electron-nucleon deep-inelastic scattering and related high-energy data including the beyond the Standard Model gauge boson, . Contrary to the dark photon case, we find no improvement in the relative to the baseline result. The finding allows us to place exclusion limits on the coupling constant of the with mass in the range to 160 GeV.
