  • Open Data: Learn how to use it, make a physics case. (The released data is not yet that interesting for BSM, but none the less interesting to get experience and give feedback). See also presentation by Kati Lassila-Perini at the kick-off meeting.

  • Usability of SMS results: SMS results are very useful for quickly checking LHC constraints without the need of event simulation. However, there exist severe limitations in the usability of the SMS interpretations provided by the collaborations, for example when only 1 mass plane is given for a 2-step topology. See these slides from the kick-off meeting for more details. We'd like to improve on these issues.

  • Long-lived particles develop public recast codes for LLP searches ... several contributions at kick-off meeting and 2nd workshop but no public code yet. Lots of discussions on simplified models and presentation of results at LHC Long-Lived Particle and Les Houches PhysTev2017 workshops. See also the LH wiki on simplified models for LLP. Action: joint sessions with LLP community workshops.

  • Delphes developments: several of the public recast codes and generally many pheno analyses rely on Delphes for the emulation of detector effects. Related with the point above, a generic treatment of long-lived particles (HSCP, displaced signatures, ...) within Delphes would be highly needed.

[2017-01-12] PhenoData database: The idea of PhenoData, the part of the HEPMDB project, is to centrally and effectively store data (digitized curves from figures, tables etc) from those HEP papers which did not provide data in arXiv or HEPData, and to avoid duplication of work of HEP researchers on digitizing plots. This database has an easy search interface and paper identification via arXiv, DOI or preprint numbers. Contact: Alexander Belyaev

  • Interpretation of resonance searches: depending on the signal assumptions, using directly the cross section ⨉ branching ratio limits from the experimental paper can be quite misleading. So far, we have no dedicated discussion of this in our Forum. See e.g. arXiv:1801.08129 for a recent relevant paper ....
 
  • BSM analysis implemented in Rivet: as from v2.5.0 efficiencies and smearing can be used in Rivet to deal with results which are not unfolded (the typical BSM case). Efficiencies are particularly relevant for leptonic analyses and/or analyses involving b-jets. The Rivet implementation allows the efficiency and smearing functions to be completely specific to each analysis. Some LHC Run 2 analyses are implemented already but need further validation and comparison to recast tools using Delphes3.

  • Correlation matrices: an example of an experiment producing a correlation matrix for systematics between bins in a single analysis, and a corresponding pheno recast making use of it in a likelihood function. Some work has started on this in GAMBIT together with people from CMS. It will be useful to have example recasts showing the usefulness of this extra info. Could an extensible approach with decomposition into correlated and fully correlated errors from identified standard error sources be agreed?

[2017-01-19] CMS NOTE-2017-001 on "Simplified likelihood for the re-interpretation of public CMS results": The note presents a procedure for the construction of simplified likelihoods for the re-interpretation of the results of CMS searches. A toy example is used to demonstrate the procedure and its accuracy in reproducing the full likelihood for setting limits. Two concrete examples, the CMS monojet and alpha_T searches, demonstrate the validity of the approach.

[2017-01-12] PhenoData database: The idea of PhenoData, the part of the HEPMDB project, is to centrally and effectively store data (digitized curves from figures, tables etc) from those HEP papers which did not provide data in arXiv or HEPData, and to avoid duplication of work of HEP researchers on digitizing plots. This database has an easy search interface and paper identification via arXiv, DOI or preprint numbers. Contact: Alexander Belyaev

 

Topics, subgroups, ongoing and proposed efforts

  • Review of tools for the BSM (re)interpretation of LHC data : see RecastingTools
Line: 43 to 50
 
  • Digitized information: Lots of useful 'data' still has to be read off from tiny paper plots (and/or is difficult to be found at all) --> Encourage as much as possible the systematic use of the new HEPData; this concerns the publication of results but also auxiliary material and -very important- performance plots. HEPData itself makes an effort to become better searchable and more user-friendly.

  • Validation material: continue and improve interaction with experimental groups on providing (auxiliary) material necessary for a rigorous validation of recast codes: well defined benchmark points, detailed MC settings (run cards!), detailed cutflows for preselection and all signal regions. NEW: A discussion / Q&A forum should be set up to give feedback on the quality of the documentation and show how well different results can be used and how much they are being used. We should review the importance of various elements, to help the time-constrained experimental analysis teams prioritise. See final discussion of the Dec 12-14, 2016 workshop.

  • BSM analysis implemented in Rivet: as from v2.5.0 efficiencies and smearing can be used in Rivet to deal with results which are not unfolded (the typical BSM case). Efficiencies are particularly relevant for leptonic analyses and/or analyses involving b-jets. The Rivet implementation allows the efficiency and smearing functions to be completely specific to each analysis. Some LHC Run 2 analyses are implemented already but need further validation and comparison to recast tools using Delphes3.

  • Correlation matrices: an example of an experiment producing a correlation matrix for systematics between bins in a single analysis, and a corresponding pheno recast making use of it in a likelihood function. Some work has started on this in GAMBIT together with people from CMS. It will be useful to have example recasts showing the usefulness of this extra info. Could an extensible approach with decomposition into correlated and fully correlated errors from identified standard error sources be agreed?
    • First progress in this direction: see talk by Nick Wardle on simplified likelihoods.

  • Example BSM analysis implemented in RIVET as a show-case for using efficiencies and smearing in Rivet. To be done in collaboration with a sympathetic analysis group from ATLAS or CMS. Ideally this would have both, an ATLAS and a CMS example. Leptonic analyses or analyses involving b-jets would be appropriate to make the case for using efficiencies.

  • Usability of SMS results: SMS results are very useful for quickly checking LHC constraints without the need of event simulation. However, there exist severe limitations in the usability of the SMS interpretations provided by the collaborations, for example when only 1 mass plane is given for a 2-step topology. See these slides from the kick-off meeting for more details. We'd like to improve on these issues.

Forum on the Interpretation of the LHC Results for BSM studies

The quest for new physics beyond the Standard Model is arguably the driving topic for Run 2 of the LHC. Indeed, the LHC collaborations are pursuing searches for new physics in a vast variety of channels. While the collaborations typically provide themselves interpretations of their results, for instance in terms of simplified models, the full understanding of the implications of these searches requires the interpretation of the experimental results in the context of all kinds of theoretical models. This is a very active field, with close theory-experiment interaction and with several public tools being developed.

With this forum, we want to provide a platform for continued discussion of topics related to the BSM (re)interpretation of LHC data, including the development of the necessary public RecastingTools and related infrastructure.

  • Example BSM analysis implemented in RIVET as a show-case for using efficiencies and smearing in Rivet. To be done in collaboration with a sympathetic analysis group from ATLAS or CMS. Ideally this would have both, an ATLAS and a CMS example. Leptonic analyses or analyses involving b-jets would be appropriate to make the case for using efficiencies.
