== List of proposed topics for session 2 ==
  *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

== session2 -> session 1 wishlist ==

  * 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  

== experimentalist's projects ==
  * 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
