Abstract
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. Published by the American Physical Society 2024
