  1. Measurement of B(D+ + ) Sadia Khalil & Sheldon Stone Syracuse University 12/07/2007

  2. Number of Tags(707 pb-1) After a correction of 1.5±0.64 % based on the fact it is easier to find tags in +  events than in generic decays, the total # of tags is 347297±677±2223

  3. MM2 Plot 103

  4. MM2 of + (Data)Case1

  5. MM2 of + and +  (Data)Case1

  6. MM2 of + (Data)Case2

  7. MM2 of + (Data)Case2

  8. BackGround Studies • E Side bands (Data) • Cont SkimMC • Radret SkimMC • DDbar SkimMC

  9. Backgrounds from MM2 for D+ → + 

  10. Backgrounds from MM2 for D+→ + 

  11. 8.04 events (Data) MM2 Plots 7.69 events

  12. (Cont31-44)MM2 Plots from Side Bands 36.9 Events 37.3 Events

  13. Cont (31-44) (within Signal E and Mbc) 19 Events 15 Events

  14. Radret MM2 Plots from Side Bands (Scaled to bgd under the D peak) 0 Events 1.5 Events

  15. 0 Events 1 Events Radret GenMC (within Signal E and Mbc)

  16. D0 D0 (20xL44+30xL31 = 4.1 fb-1) MM2 Plots from Side Bands (Scaled to Bgd under the D peak) 12 Events 1 Event

  17. 0 Events D0D0 SkimMC (within Signal E and Mbc) 10 Events

  18. MM2 Plots from Side Bands (Scaled to Bgd under the D peak) OtherD+ = One side is Tag mode and the ‘otherside’ decays to D+ which is not a signal and any of the known backgrounds 1 Events

  19. D+D- SkimMC (within Signal E and Mbc) 4 Events 0 Events

  20. Backgrounds from MM2 within -0.1<MM2<0.2
