The LHC Olympics --- Black Box "the Classic"


Warning as of 2/04/06:

In contrast to what this web page originally said, we have learned from the creator of the data set that

1) this is not quite the same model as was used in summer 2005;
2) the amount of data simulated is actually 5.3 inverse fb, not 20.

We regret this unfortunate situation and will decide what to do about it at the Winter 2006 Olympics next week.


This black box is created from the same [actually, only similar] model used in the summer 2005 LHC Olympics, but with about ten times as much data: 20
[actually, only 5.3] inverse femtobarns, about two or three years [actually, less than one] worth of LHC running time.  The model was created by the Michigan group and the data simulated by Steve Mrenna.




The old data file from the summer is HERE --- BUT it was created using a different version of PGS (for which a top-quark-antiquark pair production calibration sample is HERE) with no triggering implemented, so the old file and the new file MUST NOT BE COMBINED.  Indeed, any analysis which was done on the summer blackbox must be redone (though of course, if done correctly, it should reach the same conclusion about the underlying model!)  The old inclusive signatures files for this data set are currently here (.ps,
.pdf versions) and analysis that was done on this data set can be found at the summer workshop website.
