ATLAS/CMS Dark Matter Forum Topic: s- and t-channel simplified models, monojet-like and dijet+MET-like signatures

Interested Forum members:

  • Tim Tait
  • David Salek (ATLAS mono-jet)
  • Valerio Ippolito (ATLAS mono-jet)
  • Phil Harris (CMS)
  • Valya Khoze
  • Paddy Fox
  • Phat Srimanobhas (CMS mono-jet)
  • Alexis Kalogeropolous (CMS)
  • Uli Haisch
  • Phil Harris (CMS)
  • Kathryn Zurek (t-channel)
  • Michele Papucci (t-channel)

Task: choose generic s- and t-channel simplified models with vector and scalar mediators and produce matrix element implementation. The initial focus should be monojet- and dijet+MET-like signatures, but the models should be coherent with the EW and HF-specific models.

Timescale: needs completed by the end of January 2015

The Forum members working on this subject have the responsibility to choose a set of s- and t-channel simplified models (matrix element) that should be agreed upon by both collaborations for Run-2 searches. They will discuss and work with those responsible for the full list and for other channels to have a coherent list across final states (see OverallListAndDocumentation page) and include other experts in the discussion if necessary.

Work log and plan

January 2015: As a follow-up to the discussion on the mailing list and from existing literature, Steve Mrenna and the ATLAS/CMS Dark Matter Forum organizers have produced a first draft list of models to be modified by the Forum members. FirstListOfModelsAndQuestions20150123


2015/01/23 - First rough list of models and questions: FirstListOfModelsAndQuestions20150123

Suggested timeline and milestones

First ATLAS/CMS Dark Matter Forum meeting: 2nd week of January 2015

  • Reach agreement or implement changes with respect to the initial list.
  • Present a plan for convergence of the list
  • Start communicating with Forum members working on the subject of the implementation

Second ATLAS/CMS Dark Matter Forum meeting: last week of January 2015

  • Have a final list of selected s-channel models to serve as Run-2 benchmarks
  • Actively participate in decision of grid points and various implementations to be used

Third ATLAS/CMS Dark Matter Forum meeting: second week of February 2015

  • Prepare documentation suitable both as a reference for the internal ATLAS and CMS audiences and as an explanation for theory and non-‐collider readers.
  • Share written documentation with Forum participants and reviewers
