Upload alternative signals in the LHE format and request that any given analysis is "recast" for an alternative model.
Note: this is a request, there is no obligation for the experiments to respond.
Anyone can subscribe to an analysis to be informed of activity associated with the analysis
Experimentalists can accept the request, process these alternative signals with the full simulation, reconstruction, and analysis selection.
If authorized by their collaboration, 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 a phenomenological recasting tool.
