CMS excludes κ_VV outside 0.40-1.60 at 95% CL and constrains κ_2W and κ_2Z using VBS events with a boosted Higgs to bb decay.
PaRT achieves >50% tagging efficiency for boosted H->WW jets at 1% background efficiency, decorrelated from jet mass, with data-to-simulation scale factors of 0.9-1.0 on 138 fb^{-1} of 13 TeV collisions.
No significant excess is observed in the first search for Higgs-to-SUEP decays with leptonic W or Z bosons; cross-section limits are set across SUEP model parameters.
CMS implemented a particle-flow algorithm that reconstructs a complete list of final-state particles per collision, delivering superior performance for jets, hadronic taus, missing transverse momentum, and lepton identification up to 20 pileup interactions.
CMS sets an observed upper limit of 4.4 on the HH signal strength μ_HH in the 4b final state at 13.6 TeV, improving prior LHC results by more than a factor of two in the resolved topology.
New upper limits exclude mediator masses up to 4.5 TeV for a 50 GeV dark Higgs and up to 2.5 TeV for 150 GeV in a spin-1 mediator dark matter model, the most stringent to date for these masses.
