Skim2 SS2 Overview
3
Skim2 Processing Rate

• We have completed 221 tapes out of 500 44 done
• At full tilt, we can process about 9.8 tapes/day.
• 9 tapes/day is realistic
• With no other delays, we can finish by the end of
  May.

New GMC Subskim

• Looking for Golden-Mode Charm in the Global
  Vertex Skim
• No Cerenkov Particle ID Cuts Whatsoever
• Some linkedtracks are notCITADL tracks
• 2 skim ratio
• 10 tapes
• Can get cleansamples usingD tagging andother
  kinematiccuts

5
Possible Studies

• About 5 of the linked PWC tracks are not
  CITADL tracks
• S/N of entire sample is 0.82, so the non-CTDL
  tracks are poor quality
• CITADL is doing a good job But we knew that
  already!
• This subskim allows us to perform more accurate
  studies easily

Skim2 of SS2 Output Tapes

• Copies of FSG and FSK tapes must be handled
  through the tape copy facility
• In the future we could make extra copies of FSBD
  and FSBE with very little impact on our system
