Description
Simplified Models have become one of the standard methods to search for physics beyond the Standard Model, reducing full models with dozens of particles and hundreds of parameters down to a handful of particles and parameters, allowing for the commonalities between different models to become apparent.  

The challenge with Simplified Models is that any full model decomposes into many different Simplified Models. The spectrum of Simplified Models sometimes requires several different particles with many different parameters. Existing experimental analyses are often sensitive to these alternate Simplified Models, so there is not necessarily any additional work for the experiments to do in the limit setting process, it is only a matter of reinterpreting existing results. While the experimental collaborations can do this, it is often beyond their computing resources and the effort required in reinterpreting results could be spent in performing new analyses. 

There are multiple reasons that coordination is desirable.  First, experimental analyses often present results on related, but different Simplified Models. Next, there is no standard format to present the results from Simplified Model results. Finally, there are too many Simplified Models for every relevant experimental analysis to present efficiencies for every Simplified Model.  

This Workshop aims at stimulating more coordination of efforts between theoretical groups and between experimental efforts, starting with the formation of a Simplified Model Working Group.
The goals of this workshop are to:
  1. Define the relevant Simplified Models
  2. Prioritize Simplified Models and assign relevant topologies to different groups
  3. Decide on the format for presentation of efficiencies
  4. Define a format for analysis level cuts and create a standard procedure for reanalysis
A preliminary draft containing the goals of the workshop has been attached (Overview -> Slides).

We have reserved a block of 15 inexpensive rooms (washbasin only) in the St Genis Hostel. If you are interested, please contact Michelle (Michelle.Connor@cern.ch).
