QCD veto studies for Gen5

Last update 06/10/2005

   W transverse mass distributions for each sample (QCD veto and Ht cut are applied):

• page 1: all the events after good Si requirement with 3 or more jets,
• page 2: all the events after good Si requirement with 3 jets,
• page 3: all the events after good Si requirement with 4 or more jets,
• page 4: Ht significance for pretag events with 3 or more jets, 3 jets and 4 or more jets (S->ttbar, S+B->data),
• page 5: Ht significance for pretag events with 3 or more jets, 3 jets and 4 or more jets (S->ttbar, B->W+3,4p),
• page 6: all the events after, at least, one JP tag with 3 or more jets,
• page 7: all the events after, at least, one JP tag with 3 jets,
• page 8: all the events after, at least, one JP tag with 4 or more jets,
• page 10, 12 and 14: as page 6, 7 and 8 but all together,
• page 15, 16 and 17: as 6, 7 and 8 but normalized to the expected number of events,
• page 19, 21 and 23: as 10, 12 and 14 but normalized to the expected number of events,
• page 24: sum of the backgrounds,
• page 25: Ht significance for tagged events with 3 or more jets (S->ttbar Monte Carlo, B->all the backgrounds),
• page 26: Ht significance for tagged events with 3 jets (S->ttbar Monte Carlo, B->all the backgrounds),
• page 27: Ht significance for tagged events with 4 or more jets (S->ttbar Monte Carlo, B->all the backgrounds),
• page 28: Ht significance for tagged events with 3 or more jets (S->ttbar Monte Carlo, B->QCD background),
• page 29: Ht significance for tagged events with 3 jets (S->ttbar Monte Carlo, B->QCD background),
• page 30: Ht significance for tagged events with 4 or more jets (S->ttbar Monte Carlo, B->QCD background).
