We study in a model-independent way new neutral and charged vector bosons that could give observable signals with leptonic final states at the LHC. We show, in particular, that a charged vector W' decaying into lepton plus neutrino is accompanied by at least an extra neutral vector boson Z', nearly degenerate with the charged one. Conversely, a Z' boson with significant isospin violation cannot exist without a companion W'. To take advantage of these generic correlations, we perform a combined analysis of LHC data in the dilepton and lepton-plus-missing-energy channels, which allows us to improve the limits from independent analyses. We also develop some tools to easily deal with cases in which several heavy vector bosons with similar masses interfere. Finally, we develop a theoretically consistent framework for the study of the sequential Z' and W' benchmarks.

  1. Combination of searches for heavy vector boson resonances in proton-proton collisions at $\sqrt{s}$ = 13 TeV

    hep-ex 2026-01 conditional novelty 6.0 of 10

    A CMS combination of searches finds no heavy vector boson resonance and excludes HVT W′/Z′ bosons below 5.5 TeV (weak coupling), 4.8 TeV (strong coupling), and 2.0 TeV for VBF production at 95% CL.

  2. A common origin of the Higgs boson and the flavor hierarchies

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A unified TeV-scale model produces the Higgs as a pseudo-Goldstone boson from the same gauge deconstruction that suppresses light-family Yukawa couplings and CKM mixing while leaving PMNS mixing anarchic.

  3. The $Z'$-boson of the $B-L$ Supersymmetric Standard Model and its Large Hadron Collider Searches

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    In the BLSSM, Z' masses down to 2.24 TeV remain allowed when the boson is fat, leptophobic, or has large branching ratios to model-specific states while respecting LEP/SLC and LHC constraints.
