Constraints on the $U(1{)}_{B-L}$ model from global QCD analysis

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