Download the black box file, in the standard LHC Olympics format. It represents about 10 fb^-1 of new physics data. For more information on this format see the LHC Olympics Wiki (username: olympian, password: blackbox).
Basic counts and distributions from the black box.
Important Note: the final versions of the software used to make this box were finalized before PGS 070120 was released. The box was made with the package pythia-pgs 1.0.4 distributed through the Madgraph site. The updated PGS has an improved tau ID efficiency relative to the one that was used to produce this box! You should keep this in mind when analyzing the data.
Here are WZ events generated with Madgraph, decayed with BRIDGE, and run through the same versions of Pythia and PGS as the black box. They should help you understand the relative efficiencies for the different lepton flavors. The events that did not trigger are still in the file, so you will have to use the trigger word.
Here is the PGS param card used (it's the default).
Another note: this black box was generated with the standard LHC Olympics level 1 trigger.
Update: here are the same events, with the "Level 2" trigger in PGS turned on. This means only about 20% of the events in the "Level 1" sample are triggered. The "Level 2" trigger is unrealistically strict, but if you wish to compare with PGS backgrounds, it might reduce event counts to a manageable level.
Note: because BRIDGE currently puts all particles on-shell, invariant masses might come out narrower than expected! (Of course, there should still be experimental resolution effects from PGS.)
The next LHC Olympics meeting will be part of "Physics at LHC" at Princeton.
This black box was created by Patrick Meade, Peter Onyisi, Maxim Perelstein, and Matt Reece, with some discussion and assistance on choosing and implementing the model from a few others at Cornell.
For discussion of the event generation process, and for hints on solving the black box, see Patrick Meade's talk at the previous LHC Olympics workshop at the KITP.
