This is the WEB page summarizing the blessed results for the measurement of the sample composition of the lepton+SVT track triggers. Those have been produced for the summer conferences 2003 and have been blessed in the B Physcis Meeting on July 10, 2003.

There is a complete version of the results: HTML.

Below are the eps versions of all figures meant for downloads.

• Mass distributions subtracted using d0(SVT):
  mlsvt_td0.eps
• Signed impact parameter distribution of lepton with 4<M(l,track)<5 GeV. There are about 146,000 semileptonic b-decays in the shaded region.
  sd0_emu_m4.eps
• Signed impact parameter distribution of lepton with 2<M(l,track)<4 GeV:
  fit_sd0_m.eps
• The same, but with a logarithmic y axis:
  fit_sd0_m_logy.eps
• Signed impact parameter distribution of lepton with M(l,track)<4 GeV:
  fit_sd0.eps
• The same, but with a logarithmic y axis:
  fit_sd0_logy.eps
• Mass of muon+SVT compared with Monte Carlo normalized by fitted yields. Detector resolution has not been simulated in the Monte Carlo, as is evident from the J/psi peak:
  mass_plot.eps
• This is another rendition of the same thing but with b and c components identified explicitly. This could be useful to motivate the requirement of 2<M(l,SVT)<4 GeV to reject the direct charm component.
