Abstract: We investigate constraints on the dark photon arising from an analysis of deep inelastic scattering data. We perform extractions of parton distribution functions with and without a dark photon being present and allow the dark photon mixing parameter and mass to vary. We also include the effects of vector-meson dominance to ensure the correct photoproduction limit. By considering the variation of the total χ² arising from such extractions, we infer exclusion limits on the kinetic mixing parameter of the dark photon for dark photon mass up to 80 GeV.
