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.

  1. GeV-scale thermal dark matter from dark photons: tightly constrained, yet allowed

    hep-ph 2025-07 conditional novelty 5.0

    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...

  2. Deciphering compressed electroweakino excesses with MadAnalysis 5

    hep-ph 2025-07 conditional novelty 5.0

    MadAnalysis 5 v1.11 adds efficiency-table handling, reference-frame observables, and statistical tools, then applies them to two ATLAS Run-2 analyses of compressed electroweakino signatures inside the NMSSM.

  3. Interpretation of LHC excesses at 95 GeV and 152 GeV in an extended Georgi-Machacek model

    hep-ph 2025-11 unverdicted novelty 4.0

    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.

  4. Indications for New Higgs Bosons

    hep-ph 2026-05 unverdicted novelty 3.0

    Excesses in di-photon and other channels at the LHC indicate possible new scalars near 95 GeV and 152 GeV, with the 152 GeV candidate fitting an SU(2)_L triplet model that also affects top-quark distributions.

  5. Search for Dark Matter in 2HDMS at LHC and future Lepton Colliders

    hep-ph 2025-04 unverdicted novelty 3.0

    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.
