  1. Update:Run1 vs Run2 CC inc &First look at Water-out/Water-in Erez Reinherz-Aronis and Rajarshi Das (w/ Walter Toki) May 9, 2011

  2. Outlook • Samples and POTs • Bunch structure • Run1 vs Run2 • Run 1: Data vs MCp4 • Run 2: Data vs MCp4 • MCp4: Run1 vs Run2 • Data: Run1vs Run2 • Water-out/Water-in • Data: Ratio Water-out/Water-in vs expectation

  3. Samples and POTs • DQ sample were used • CC Inclusive Selection: • Highest momentum negative charge track in a bunch • Begins in the P0D • (no TPC pulls cut)

  4. Bunch timing • Run2 has Double-Triple bunch structure • 1st = Run36; 2nd, 3rd = Run37/8 Run 2 Run2: Run 37→38 Run 36 Run 1 Run1: Run 31 → 34

  5. Run1 vs Run2Run 1: Data vs MCp4Run 2: Data vs MCp4MCp4: Run1 vs Run2Data: Run1vs Run2

  6. Run1 Data vs MCp4CC inc - X, Y, Cosθ, φ Normalized by POT

  7. Run1 Data vs MCp4Z, Neg Trk Momentum • Normalized by POT • Start position of Highest momentum Neg. Trk in the P0D • The dashed lines represent the water-target limits

  8. Run2 Data vs MCp4CC inc - X, Y, Cosθ, φ Normalized by POT

  9. Run2 Data vs MCp4Z, Neg Trk Momentum • Normalized by POT • Data/MCp4 = 8273/8521 = 0.97±0.02

  10. MCp4 Run1 vs Run2CC inc - X, Y, Cosθ, φ Run1 water Run2 water Normalized by POT

  11. Mcp4 Run1 vs Run2Z, Neg Trk Momentum • Normalized by POT • Run1/Run2 = 111955/108661 =1.030±0.004

  12. Data Run1 vs Run2CC inc - X, Y, Cosθ, φ Run1 water Run2 water Normalized by POT

  13. Data Run1 vs Run2Z, Neg Trk Momentum • Normalized by POT • Run1/Run2 = 6062/5673 =1.07±0.02

  14. Z distribution checks: XY Run1 water Run2 water Normalized by POT Beam position and direction X

  15. Water-out/Water-inData ratio vs expectation

  16. Samples and POTs • DQ sample were used

  17. Data CC inc: X, Y, Cosθ, φ Run1 Run2 water Run2 air Normalized by POT

  18. Data CC inc: Neg Trk Momentum • Run1 • Run2 water • Run2 air • Normalized by POT • Note: Run2 air is reconstructed as water • No TPC pull used

  19. Z position distributions Run1 3588 Run2 water 3358 Run2 air 2573 Run1/Run2 = 1.07±0.02 • Start position of Highest momentum Neg. Trk in the P0D • The dashed lines represent the water-target limits

  20. Water-out/Water-in ratio 0.94±0.09 0.70±0.02 0.94±0.05 • Water-target measured ration 0.70±0.02 • Expected ration from material list: 0.68 • Dashed lines are the water-target limits

  21. Summary • Run1 vs Run 2: • MCp4 Run1/Run2 ~3% higher • Data Run1/Run2 ~7% higher • Maybe there is some Z difference (within limit stat.) • Water-out/Water-in ratio measured 70 ± 2 % (expect 68 %) • Future plans: • Data/MC ratio vs P0Dules • MCp4 – study TPC pulls
