Dijet and electroweak limits on a $Z'$ boson coupled to quarks

High Energy Physics - Phenomenology 2024-04-30 v2

Abstract

An insightful way of presenting the LHC limits on dijet resonances is the coupling-mass plot for a ZZ' boson that has flavor-independent quark interactions. This also illustrates the comparison of low-mass LHC sensitivity with constraints on the flavor-independent ZZ' boson from electroweak and quarkonium measurements. To derive these constraints, we compute the ZZ' mixing with the ZZ, the photon, and the Υ\Upsilon 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 ZZ' masses from 5 GeV to 5 TeV.
