Topics for Consideration

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

• what has been learned so far from NNLO calculations
• for jj, for Hj
• what common elements exist that will be useful for future calculations
• how can programs be used by non-authors?

• Status of automated calculations
• EWRC
  • automatic inclusion of EW effects →test cases
  • Features of the TeV scale and of the transition from 8 TeV to 13 TeV
    • Photon induced processes (like gamma gamma → WW)
    • W/Z emission
• NLO PS → NNLO PS
• exclusive jet cross sections→what does the data tell us?
• scale choices: motivation/justifications for HT/2

• utility of/use of META PDFs

• extrapolation uncertainties to full sigma
• WW as poster child

• more on Les Houches tight isolation accord→theory with Frixione isolation = theory with NLO fragmentation with experimental fixed cone isolation (=data)

• physics of jet R variation
• jet sub-structure tools and how they can be part of everyday analyses (Overlaps with NLO/SM and Tools/MC a bit with Higgs (e.g. VBF tagging)
• How to define quark/gluons at fixed order? (i.e. flavored jet algorithms)
• Tests of quark/gluon taggers? (ATLAS/CMS/theory)
• Why do current parton showers give such large discrepancies in quark/gluon tagging performances?
• Data available to tune quark/gluon taggers? (RIVETized analyses?)
• Key future measurements to be made? (at LHC or even in archival data?)
• Quark/gluon enriched samples? (e.g. dijet vs. gamma/W/Z + jet)
• Can NⁿLO/NⁿLL calculations improve our understanding?
• Impact of soft QCD (underlying event) and pileup?

• How to improve and make best use of differential cross section measurements?

• Parton shower systematics
• Multijet merging systematics
• Tuning in presence of matching + merging
• Matching with photons and QED corrections
• cross generator comparison, possibly ttbar+jets (other channels welcome)

• Intimately related to this is the issue of fiducial cross sections. This has both theory/modelling/MC aspect
• Presentation of LHC results; reinterpretation studies; feedback from experimentalists; update of the Atom/CheckMate/MadAnalysis 5

• Compressed spectra in SUSY: alternative signals
• Theories where non-color particles cancel the quadratic divergence:The Twin Higges et al. How to look for these?
• BSM simulation at NLO in QCD
• Standardizing cross section information in the SLHA format (finalizing what has been initiated in 2013)
• Superboosted tops
• Vector-like Quark/Top partner searches: recommendation for presentation of searches for weak single production
• New Heavy gauge bosons: Prospects/priorities for run-II
• Compositeness scenarios: possibile to present results in terms of a useful simplified parametrisation (like MSSM/pMSSM etc)?
• Is the current status of boosted object reconstruction techniques sufficient for Run-II BSM searches? e.g. Is experimental b-tagging good enough in the boosted H/t kinematic regime?
• Do we need new techniques for leptonic and semi-leptonically decaying boosted objects?
• EFT approach to new physics and DM: Signals & limitation
• non-EFT approach to DM physics

• Effective field theory approach to Higgs searches at the LHC.
• EFT implementation in Monte Carlo
• Fiducial Higgs cross sections at the LHC
• 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 ?
• 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?
