Search for heavy diboson resonances in semileptonic final states in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
abstract
This paper reports on a search for heavy resonances decaying into $WW$, $ZZ$ or $WZ$ using proton-proton collision data at a centre-of-mass energy of $\sqrt{s}=13$ TeV. The data, corresponding to an integrated luminosity of 139 $\mathrm{fb^{-1}}$, were recorded with the ATLAS detector from 2015 to 2018 at the Large Hadron Collider. The search is performed for final states in which one $W$ or $Z$ boson decays leptonically, and the other $W$ boson or $Z$ boson decays hadronically. The data are found to be described well by expected backgrounds. Upper bounds on the production cross sections of heavy scalar, vector or tensor resonances are derived in the mass range 300-5000 GeV within the context of Standard Model extensions with warped extra dimensions or including a heavy vector triplet. Production through gluon-gluon fusion, Drell-Yan or vector-boson fusion are considered, depending on the assumed model.

A Busy Higgs Signal
Higher-order Higgs couplings induce an electroweak-symmetry-breaking enhancement that makes Higgs-rich final states the dominant signals for scalar resonances and opens resonant multi-Higgs channels above a couple of TeV.

Alignment and Enhanced Multi-Higgs Production
In extended scalar sectors near the alignment limit, higher-dimensional interactions can make two-, three-, or four-Higgs final states the dominant discovery mode at the LHC via gluon fusion.

Stopping Dark Mesons in Their Tracks with Long-Lived Particle and Resonant Signatures
Recast LHC searches yield a ~1.2 TeV lower bound on long-lived charged dark mesons and show that anomaly-driven diboson resonances can reconstruct UV parameters like dark flavor and color numbers from IR measurements.

Characterisation at the HL-LHC of Long-lived Heavy Neutrinos in Gauge Extensions of the Standard Model
Displaced heavy-neutrino signals in LRSM and U(1)B−L remain accessible at the HL-LHC, with parton-level mass, lifetime, and AFB handles in low-background regions.

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