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
