• Effective field theory approach to Higgs searches at the LHC
• EFT implementation in Monte Carlo
• Fiducial Higgs cross sections at the LHC: why, how, and what can be learned
• Synergy of electroweak precision and Higgs data
• Triple gauge couplings at the LHC: how to make the analysis better and more model-independent.
• Presentation of limits from heavy Higgs searches on multi-Higgs models.
• Complementarity between non-standard Higgs searches and precision Higgs measurements
• Extra Higgs (light or heavy) searches: which decay channels are not covered?
• Scalars approximately mass-degenerate with the 125 GeV Higgs boson
• Higgs studies in the off-shell regime: on-shell and off-shell interference effects, impact on heavy Higgs signal strength measurements, EFT vs simplified models.
• Prospects for NMSSM Higgs Bosons with Run II
• “Exotic” decays of h(125) - what is doable with Run II and how ?
• Exotic production of h(125), disentangling from SM production
• probing h(125) CP (beyond h→ZZ: fermionic h decays, ttH, …)
• Higgs and dark matter.
• Renormalization group effects in the dim 6 EFT space, impact on searches for new physics?
• status of double Higgs production searches: is there something left to do?
• WW scattering, unitarization studies

• identify worst systematics for simulating Higgs signals at the LHC
• discuss data driven determination of ggH contamination in VBF searhces
• discuss tuning of bbh associated production predictions using bbZ data

• Apyan Aram (CMS)
  • heavy changed higgs searches for Run2, in particular with H+→chi+chi0 and H+→tau+ nu
• Bluj Michal (CMS) (can't be in Les Houches unfortunately)
  • measurement of the h((125) CP properties with h→2tau
• Carrillo Camilo (CMS)
  • search for a low mass h→ 2gammas (down to 60 GeV). The main interest is the exploration of models that this search could constrain.
• Chanon Nicolas (CMS)
  • Higgs EFT: Trying out Higgs basis (maybe with aMC@NLO) for gluon fusion and connexion with ttH
  • Higgs EFT: EFT studies connecting VBF/VH and aTGC in diboson; could be done with new EFT tool at NLO (Benjamin Fuks et al)
  • Double Higgs in NMSSM
• Courbon Benoit (CMS)
  • NMSSM/BSM Higgs bosons, final states with photons for Run II
• Devdatta Majumder (CMS)
  • Resonant production of diHiggs in BSM with both Higgs bosons decaying to bb. Improbved tagging of high pT H→b using jet substructure and flavour-tagging techniques.
• De Filippis Nicola (CMS)
  • “monoHiggs models”: DM candidates produced in association with a Higgs decaying into 4l. motivated by arXiv:1312.2592
• Juste Aurelio (ATLAS)
  • FCNC Higgs interactions
  • searches for BSM Higgs bosons in top quark final states
• Nikitenko Alexander (CMS):
  • BSM bbA: simulation uncertainties; can bbZ help to reduce bbA uncertainties; gg→A “bkg” to bbA;
  • MSSM heavy H/A→sparticles: can it complement the direct sparticles searches ?
• Oliveira Alexandra (CMS)
  • di-higgs physics in gluon fusion at LHC; would like to understand in which BSM scenarios non-resonant VBF hh could be enhanced more than GF hh
• Pollard Chris (ATLAS)
  • involved in ATLAS diboson resonance searches (VV, VH, HH), with H→bb and vector bosons decaying to both leptons and hadrons, including BSM A/H decaying to these final states. Most of his effort currently goes towards high-pt top/boson ID and reconstruction: b-tagging, substructure, reconstruction of close-by leptons and jets
  • most interested in discussing new reconstruction techniques and the interpretation of analyses making use of them.
• Sabes David (CMS)
  • light scalar bosons in SUSY models
• Ulrich Goerlach (CMS)
  • evaluate what NMSSM benchmark scenarios proposed in arXiv:1408.1120 (Maggie et al) can be measured at RunII
