The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have collected a total of 2461 pb-1 of e+e- collision data at centre-of-mass energies between 189 and 209 GeV. The data are used to search for the Standard Model Higgs boson. The search results of the four collaborations are combined and examined in a likelihood test for their consistency with two hypotheses: the background hypothesis and the signal plus background hypothesis. The corresponding confidences have been computed as functions of the hypothetical Higgs boson mass. A lower bound of 114.4 GeV/c2 is established, at the 95% confidence level, on the mass of the Standard Model Higgs boson. The LEP data are also used to set upper bounds on the HZZ coupling for various assumptions concerning the decay of the Higgs boson.

The 95 GeV Excess in Models with Two Higgs Doublets plus One Singlet: Model Distinction via Four-top Final States and Triple Higgs Couplings
Using the 95 GeV excess benchmarks, four-top production at HL-LHC and di-Higgs production at ILC500 can distinguish the N2HDM from the 2HDMS for pseudoscalar-mixing angles beyond a computed 'α4 limit'.

Deciphering compressed electroweakino excesses with MadAnalysis 5
MadAnalysis 5 v1.11 adds validated recasting of two ATLAS compressed-electroweakino searches and shows that a proposed NMSSM scenario fits the soft-lepton and monojet excesses less well than simpler models.

Searching for Di-Higgs Signatures of Light Charged Scalars
A roughly 130 GeV charged Higgs explaining the ATLAS t to bH+ excess and B-meson anomalies can be constrained, and perhaps discovered, by recasting SM di-Higgs 4b searches at the LHC.

Vacuum Instability and False Vacuum Decay Induced by Domain Walls in the N2HDM
Domain walls in the N2HDM can erase the barrier around the electroweak vacuum, making long-lived metastable vacua decay classically and excluding parameter points previously considered viable.

Mono-X Signal Characterization from Two-component Dark Matter Using a Convolutional Neural Network
A 1D multi-channel CNN trained on normalized histograms of simulated mono-jet and mono-Z events can partially classify one- versus two-component dark matter and regress masses, but only in a background-free, model-spe...

GeV-scale thermal dark matter from dark photons: tightly constrained, yet allowed
In a dark-photon-mediated Dirac fermionic DM model, only narrow resonant regions with small dark-sector coupling allow the candidate to saturate the full relic density while evading current direct and indirect detecti...

Deconstructing resonant Higgs pair production at the LHC: effects of coloured and neutral scalars in the NMSSM test case
In the NMSSM, interference between heavy Higgs resonances, SM top loops and stop loops can strongly distort the di-Higgs invariant mass spectrum, and a diagram-by-diagram decomposition makes these distortions interpretable.

Interpretation of LHC excesses at 95 GeV and 152 GeV in an extended Georgi-Machacek model
A minimally extended Georgi-Machacek model accommodates the LHC excesses at 95 GeV and 152 GeV while preserving the 125 GeV Higgs signal and the electroweak rho parameter near unity.

Signals of New Resonances from Di-Lepton Non-Universality in the Bottomonium Mass Region at the Large Hadron Collider
Narrow spin-zero bosons with chirality-violating couplings can produce large di-tau non-universality in the bottomonium mass region at the LHC while preserving universality at e+e- colliders.

Search for Dark Matter in 2HDMS at LHC and future Lepton Colliders
Benchmarks in the 2HDMS model with light to heavy dark matter masses are identified under all constraints and shown to have better discovery prospects at future lepton colliders than at the HL-LHC via cut-and-count analyses.
