Overview
RECAST is a framework for extending the impact of existing analyses performed by high-energy physics experiments.

  1. Anyone can add analyses to the Analysis Catalog
  2. Anyone can upload alternative signals in the LHE format and request that any given analysis is "recast" for their alternative model. While this may typically be a theorist, experimentalists may also submit requests the RECAST framework to see if other analyses already exclude the signal they are interested in.
  3. Anyone can subscribe to an analysis to be informed of activity associated with the analysis
  4. Experimentalists can accept the request, process these alternative signals with the full simulation, reconstruction, and analysis selection. If they are authorized by their collaboration, then they can respond with an authoritative result for the selection efficiency and cross-section limits for the alternative signal. Note, anyone can provide a non-authoritative result, for instance one based on fast simulation.
  5. Anyone can view the results associated with a request.

For more information, see the About page and the original White Paper.

The workhorses of the RECAST framework are the back-ends, which processes the new signal in order to obtain the selection efficiency and cross-section limits. This may either be a person doing the work manually by downloading the LHE file from the website or an automated back-end that uses the RECAST API. See the Developers page for details.
