| contents | An insightful way of presenting the LHC limits on dijet resonances is the coupling-mass plot for a $Z'$ boson that has flavor-independent quark interactions. This also illustrates the comparison of low-mass LHC sensitivity with constraints on the flavor-independent $Z'$ boson from electroweak and quarkonium measurements. To derive these constraints, we compute the $Z'$ mixing with the $Z$, the photon, and the $Υ$ meson, emphasizing the logarithmic dependence on the masses of the new electroweak-charged fermions (``anomalons") required to cancel the gauge anomalies. We update the coupling-mass plot, extending it for $Z'$ masses from 5 GeV to 5 TeV. |
