ATLAS/CMS Dark Matter Forum Topic: T-channel simplified models

Task: chose generic t-channel simplified 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 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 (see OverallListAndDocumentation page) and include other experts in the discussion if necessary.

Sub-topics and questions

1. SUSY-inspired models vs non-SUSY-inspired models? (avoid duplicating SUSY simplified models)
2. t-channel, scalar mediator
3. t-channel, vector mediator: why isn't this a standard choice in the literature? Should we include it?

Work log and plan

December 2014: Steve Mrenna and the ATLAS/CMS Dark Matter Forum organizers have produced a first document draft with three (?) models and a proposal of grid scan points as a starting set.

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 t-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
