Many extensions of the standard model contain an extra $$U(1{)}^{{'}}$$ gauge group with a heavy $${Z}^{{'}}$$ gauge boson. Perhaps the most clear signal for such a $${Z}^{{'}}$$ would be a resonance in the invariant mass spectrum of the lepton pairs to which it decays. In the absence of such a signal, experiments can set limits on the couplings of such a $${Z}^{{'}}$$, using a standard formula from theory. We repeat its derivation and find that, unfortunately, the standard formula in the literature is a factor of 8 too small. We briefly explore the implication for existing experimental searches and encourage the high-energy physics community to reexamine analyses that have used this formula.
