LHC Higgs Cross Section Working Group 2 - Higgs Properties


  • Next meeting: * WG2 session in Dec 2018 general meeting [[https://indico.cern.ch/event/740110/][December 10]


  • PO
    • Overview of effective POs and tools for extraction from measurements
    • Reweighting code to apply to existing MC
    • HiggsPO model available in Madgraph with NLO QCD corrections for VH/VBF production

  • EFT
    • Tools: Implementation of Warsaw basis in FeynRules (available) with NLO QCD corrections in Madgraph (in development)
    • Validity (for discussion): defining the region of ci vs Lambda; square term gives an estimate of the uncertainty from higher powers of 1/Lambda
    • Note on STXS->EFT mapping (available)
    • Standard procedure for combined fit to Higgs+EW+Top data (for discussion)
