Abstract

We perform the first global QCD analysis of electron-nucleon deep-inelastic scattering and related high-energy data including the beyond the Standard Model U(1)BLU(1)_{B-L} gauge boson, ZZ'. Contrary to the dark photon case, we find no improvement in the χ2\chi^2 relative to the baseline result. The finding allows us to place exclusion limits on the coupling constant of the ZZ' with mass in the range MZ=2M_{Z'} = 2 to 160 GeV.
