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.

If you have questions or want to contribute, contact Sabine Kraml, sabine.kraml@gmailNOSPAMPLEASE.com, or the whole steering group via info-LHC-interpretation-organisers@cernNOSPAMPLEASE.ch.

Meetings

RAMP seminars

RAMP stands for "Reinterpretation: Auxiliary Material Presentation". It is a new series of short meetings throughout the year, where young experimentalists present the material for their analyses in a ~15-20 min talk, followed by a discussion with potential (re)users. The aim is to create more direct experiment-theory interaction, and to give more visibility and recognition to the effort of preparing and providing extensive material for reinterpretation. The kick off is on 9 April 2021, see here for the schedule

Examples of recast studies

  • This list of recent RecastingStudies may serve as a feedback to the experiments about the use of their results and the information they provide.

  • 'Best practice' guide: we remind all colleagues doing recasts that they, too, should provide their codes and supplementary info to the community/experiments (via HEPData where appropriate, or via our Zenodo community), to make it easier for others to repeat and/or re-use their results.
