Preliminary list of topics for 2021

(accessible to everyone, editing rights to conveners and organizers)

Session 1

Jet substructure techniques:

  • Interplay of jet substructure with other groups (e.g. jet substructure for EW measurements like VBF, semileptonic VV, etc.)
  • Snowmass jet substructure report (JSS at future colliders) [work + discussion]
  • What can we do with previous colliders, in light of the LHC [discussion]
  • Comparing new unfolding methods
    • Accord on unbinned results (?)
  • Probing the latest MC generators (PB algorithm, PANScales, Deductor…) with jet substructure
    • Finite N_C, beyond LL, …

Techniques and calculations for SM phenomenology:

` * Calculations:

  • expected precision for fundamental Standard Model processes at 14 and 100 TeV; what calculations are needed to match this precision?
  • 2→3 at NNLO; status/challenges/prospects
  • theory uncertainties; more rigorous estimates? correlations?
  • theoretically sound definition of FONLL at the differential level, beyond incl. cross sections?
  • PDFs:
    • followup on PDF4LHC15 benchmarking exercise; better understanding of tolerances, tensions
    • EW corrections/EW PDFs; how to provide consistent calculations
    • small x resummation; what is HERA trying to tell us?
    • EIC; what will EIC tell us? how do we prepare for that?
  • Higgs:
    • understanding the SM for high Higgs pT; role of top mass corrections/scheme (MSbar vs on-shell); improving channel sensitivities
    • polarisation measurements (for diboson/VBS as well)
  • Top:
    • MSbar vs on-shell
    • ttW; tension; can new calculations resolve it?
  • Monte Carlo:
    • Non-perturbative uncertainties
      • common hadronisation interface and variations
      • theoretical understanding
      • differences in tuned comparisons
      • pheno impact for certain classes of processes (e.g. VBF/VBS)
    • Shower accuracy studies
      • comparing different schemes on hogher orders, evaluate phenomenological impact
      • Subleading colour and interplay with colour reconnection
      • New sampling methods and algorithms versus machine learning techniques
      • Accuracy of merging resummed calculation versus ME+PS paradigms
    • Photon physics, modelling of fragmentation
    • Heavy flavour matching
      • review of existing measurements
      • Connecting precision calculation, fragmentation and decays
      • partons at 100 TeV
    • Common LHC event bazaar
    • Status and needs for electroweak corrections and radiation in shower algorithms
  • Jets:
    • flavor tagging of jets; matching what theorists can predict (IR safety) and what experimentalists can measure
