==== Some of the topics from 2015 that can be carried over to 2017 ====

== Please ADD and EDIT (heavily)==

 === SM and N(N)LO ===


== NNLO: Attacking the 2015 Les Houches wish list ==
       *what has been learned so far from NNLO calculations
       *what common elements exist that will be useful for future calculations
       * how can programs be used by non-authors?

== What's left at NLO? ==
    *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

== PDFs ==
    *utility of/use of META PDFs

== Fiducial cross sections ==
    *extrapolation uncertainties to full sigma

== Photons ==
    *more on Les Houches tight isolation accord->theory with Frixione isolation = theory with NLO fragmentation with experimental fixed cone isolation (=data)

== Jets &  Quark/Gluon Discrimination ==
  *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 N<sup>n</sup>LO/N<sup>n</sup>LL calculations improve our understanding?
  * Impact of soft QCD (underlying event) and pileup?


==  Interface SM/BSM ==
 

== Presentation of LHC results == 
   * 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

== Joint exercises between SM and BSM->how to find BSM (or not) given limits of SM precision ==



== BSM Physics/ Including non Standard Higgs ==

  * Compressed spectra 
  * 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
  *Effective field theory approach to Higgs searches at the LHC. Simplified approach with fewer parameters  that can be  realistically implement by experiments.
  *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. 
  *Heavy higgs searches: which decay channels are not covered?
  *Higgs studies in the off-shell regime: EFT vs simplified models.
  *Complementarity between non-standard Higgs searches and precision Higgs measurements
  * MSSM low tab(beta) scenarios and Higgs decay modes to be expoited at Run II
  * Prospects for Heavy Higgs decays to charginos/neutralinos at Run II
  * Prospects for NMSSM Higgs Bosons with Run II
  * 2HDM - benchmarks; 2HDM with Dark Matter
  * "Exotic" decays of h(125) - what is doable with Run II and how ?
  * probing h(125) CP (beyong h->ZZ: fermionic h decays, ttH, ...) 
  * Higgs and DM: h->invisible,...
  * Higgs studies in the off-shell regime: on-shell and off-shell interference effects, impact on heavy Higgs signal strength measurements
  * Renormalization group effects in the dim 6 EFT space, impact on searches for new physics?
  * status of HH searches: is there something left to do?
  * precision measurements (FCC-ee/ILC) vs heavy Higgs searches
  * ...
