Topics for Consideration

(Editing this page requires special privileges: Conveners, organisers)

session 1

  • Loops,Multilegs,Jets
  • PDFs:
    • dealing with scale uncertainties in PDF fits
    • benchmark studies for current generation of PDFs, e.g. top distributions
    • dealing with tensions in LHC data, i.e. ATLAS jets vs CMS jets, top distributions
      • does each group have the same reaction to the tensions?
      • how to get the greatest knowledge from distributions with tensions?
    • dealing with NNLO grids (NNLOJET)
  • Parton Showers:
    • LH17 showed that PS predictions agree well with each other when input parameters are synchronized; reasonable physics choices then lead to differences; can we establish the limit of what these reasonable physics choices are?
  • ME+PS:
    • better understanding of limits of precision for ME/ME+PS calculations
    • uncertainties in matching PS with ME
    • better understanding of 'reasonable' scale uncertainties at NNLO
    • precision predictions in the high pT frontier
  • Progress with higher order calculations:
    • any benchmarking, for example DY at NNLO?
    • improvements for evaluation of 2→2 at NNLO
    • loopedia
    • outlook for 2→3 NNLO
    • 3-loop, e.g. Higgs rapidity
    • compact expressions at the amplitude level
    • ntuples for NNLO
  • Jets: Where is quark/gluon discrimination useful? How does it perform? Examples:
    • PDFs
    • VBF
    • X→gg
    • Susy cascades
    • ISR tagging
    • W tagging
    • top tagging
  • Higgs
  • SM Issues
    • Parton shower and underlying event related systematics in Higgs measurements for signal and background (together with Loops,Multilegs,Jets)
    • Prospect of quark/gluon jet tagging for VBF (synergy with Jets session)
    • Predictions+uncertainty models for backgrounds to ttH production: tt+HF, ggH+HF, tt+V
    • Background function choice for H→gamgam and H→mumu: how to evaluate the functional choice systematics
    • STXS:
      • Brainstorming on “STXS for Higgs decays” or something similar for decay propery measurements
      • Updates on STXS for production
    • Probing Higgs Width and Top Quark Yukawa Coupling from ttH and tttt
    • Higgs pair production and self-coupling observables, top quark mass-scheme uncertainties
    • EFT description of Higgs production
  • MC and Tools
    • ttbar: mismodeling of top pt and an angular distributions
    • W-mass and precise EW measurements: where are the bottlenecks?
    • …more to come…

    • Generative models for HEP
  • Tools&MC
    • Global fits / recasting / scanning spaces
    • Analysis preservation
