2015:topics
This is an old revision of the document!
SM and N(N)LO
NNLO: Attacking the 2013 Les Houches wish list
- 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?
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
- WW as poster child
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 NnLO/NnLL calculations improve our understanding?
- Impact of soft QCD (underlying event) and pileup?
Off-Shell Higgs
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 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
- 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
