...Urs, I am sorry but I could not resist.
These are very preliminary results for the yields on data. The amount of
data used is a bit less than 2fb-1 that correspond to the files in
/u/ec/ursl/d/output/sx-072402/AlleEvents-*.root
The tables with the yields per single mode are
http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-2.html Dstar
http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-3.html Dstar0
http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-4.html Dc
http://www.slac.stanford.edu/~daniele/vub/modes/sxModes-5.html D0
The last three raws of each table are the sum of all modes with 1) no cut,
2) cut on the single mode purity (recalculated) >10%, 3) cut on the single
mode purity (recalculated) >20%.
Comments:
- Dstar: yields similar to the old production ones
- Dc, Dstar0, D0: everywhere gain in yields, especially in Dc
- putting all together the purity seems to be lower than before (due to
skims?). Probably a reoptimization could be needed.
- I tried to evaluate the gain in statistics looking at the events with a
lepton in the geometrical acceptance. It seems that we have a
30%-50% gain in yields => more than 500K events in 85 fb-1
