New Abelian vector bosons can kinetically mix with the hypercharge gauge boson of the Standard Model. This letter computes the model-independent limits on vector bosons with masses from 1 GeV to 1 TeV. The limits arise from the numerouse+e−experiments that have been performed in this energy range and bound the kinetic mixing byϵ≲0.03for most of the mass range studied, regardless of any additional interactions that the new vector boson may have.
