Cross Sections for QCD events
All events are generated by pythia. Cross sections were found by
averaging the cross sections found in MCEvtInfo object in each
event in each sample. For each QCD sample, about 2000 events were used
to calculate cross sections. For the signal events, about 200 events
were used. More events may be used for better results ON REQUEST.
(MCC99-I cross sections can be found here.)
