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 $\Upsilon$ 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 $Z'$ masses from 5 GeV to 5 TeV.

  1. Quark-universal $U(1)$ breaking scalar at the LHC

    hep-ph 2025-06 conditional novelty 6.0 of 10

    In a quark-universal U(1)_B model, the scalar φ that breaks the symmetry can be discovered first through its diphoton decay, and its rate can explain the 95 GeV diphoton excess.

  2. Probing Leptophobic Dark Sectors via Gravitational Wave Signatures

    hep-ph 2025-08 unverdicted novelty 4.0 of 10

    A gauged U(1)_B extension of the Standard Model is claimed to produce observable gravitational waves from a first-order phase transition, with dark matter around 8-12 TeV.
