  1. 20080701 Comparison of old vs. new data (Bst-ntuples) > old data: L > 1.35 fb-1 (redcrosses) > new data: L > 1.35 fb-1 , p17 included (black histo.) > most of distributions are for B0s -> J/f signal window events with sideband windows subtraction > Using a NN-without-PID and a cut of 0.6 > Some distributions, marked with are analysed further. For that, Blt-ntuples are sometimes used. 1

  7. Taggers :

  8. Bst-ntuples, L<1.35 red, L>1.35 black Soft Muon Tagger Order of variables: decision , dilution, likelihood, tag type

  9. Bst-ntuples, L<1.35 red, L>1.35 black Soft Electron Tagger Order of variables: decision , dilution, likelihood, tag type

  10. Bst-ntuples, L<1.35 red, L>1.35 black Jet Charge Tagger Order of variables: decision, dilution, jet-charge, tag type 1

  11. Blt-ntuples 0.26 JQT jet-type vs. “L00 efficiency” 1 Errors reflect the difference between the results obtained at two sets of Signal/SB windows B0s J/ SB subs. signal events 0d 0h 0i 0j-p13 p14-17 SB1: 5.2861-5.3131 Signal: 5.3400-5.3940 SB2: 5.4211-5.4481 SB1: 5.175 - 5.202 Signal: 5.3400-5.3940 SB2: 5.547 - 5.575 p13  The variation of the JQT performance follows approximately that of the L00 # JQT-trks with L00 / # JQT-trks # jet-type[1+2] / # jet-type[1+2+3] Integrated L (fb-1)

  12. Bst-ntuples, L<1.35 red, L>1.35 black Same Side Tagger ( NN – SSKT ) Order of variables: decision, dilution

  13. COT hits:

  14. Blt-ntuples, L<1.35 red, L>1.35 black # axial hits highest pt  # stereo hits highest pt  # axial hits highest pt K # stereo hits highest pt K  L>1.35 data show wider, less peaked to higher values, distributions which may be a reflection of a higher density of charged tracks

  15. Further analysis of some distributions:

  16. Bst-ntuples, L<1.35 red, L>1.35 black 2  The use of the bad-calibrated PID in the L>1.35 sample does produce some effect on pt() Bst, NN-with-PID, 0.6 Bst, NN-without-PID, 0.6 pt() pt()

  17. 3  The use of the bad-calibrated PID in the L>1.35 sample does not produce a significant effect to the d0 J/ distribution Bst-ntuples, L<1.35 red, L>1.35 black 2 Bst, NN-with-PID, 0.6 Bst, NN-without-PID, 0.6 d0(J/) ( > 0) d0(J/) ( > 0)

  18. 3  In addition, it seems that the lower L00 hit content of the  tracks in L>1.35 is playing also no role in the d0(J/) distribution Blt-ntuples, L<1.35 red, L>1.35 black The 2 ,s w/ L00-hit No L00-hit require. d0(J/) d0(J/)

  19. 4  The use of the bad-calibrated PID in the L>1.35 sample does not produce a significant effect to the fmass distribution Bst, NN-with-PID, 0.6 Bst, NN-without-PID, 0.6 Bst-ntuples, L<1.35 red, L>1.35 black mKK mKK

  20. 4  In addition, it seems that the lower L00 hit content of the tracks in L>1.35 is playing also no role in the fmass distribution Blt-ntuples 0.26, L<1.35 red, L>1.35 black The 2 K,s no L00-hit No L00-hit require. The 2 K,s w/ L00-hit mKK mKK mKK

  21. Blt-ntuples, L<1.35 red, L>1.35 black # axial hits highest pt K # stereo hits highest pt K 4 # (Axial+Stereo): 82 < hits < 92 highest pt K 80 < hits < 90 the 2nd K  restricting to the same number of COT hits seems to help in the comparison; however the statistics is poor mKK
