We introduce novel collider searches which can significantly improve the LHC reach to new gauge bosons Z' with mixed anomalies with the electroweak (EW) gauge group. Such a Z' necessarily acquires a Chern-Simons coupling to the EW gauge bosons and these couplings can drive both exotic Z decays into Z'γ if the new gauge boson is sufficiently light, as well as Z' decays into EW gauge bosons. While the exotic decay rate of the heavy Z into Z'γ is too small to be observed at the LHC, for a light Z', we demonstrate the potential of a lepton jet search in association with a photon to probe the rare decay Z → Z'γ.
