]]> Number of Jets For Multiple Vertices 2004-09-15T19:56:20Z 2004-09-15T13:56:20-06:00 tag:harv11.fnal.gov,2004:/hlogs/SecVtx/5.199 2004-09-15T19:56:20Z Here are some plots showing the number of jets in two categories: Red: Number of taggable jets Blue: Number of taggable jets with at least one good track from the P.V.

  • Red: Number of taggable jets
  • Blue: Number of taggable jets with at least one good track from the P.V.
    • This is to examine whether we can tell if there are jets from other vertices getting into our jet list. This has implications for when we are looking at the mistag matrix, because the rate that we want is the number of positive tags over the number of jets, both of which are from the highest sum pt z vertex. However, if there are many jets that come from other interactions, the total number of jets will increase while the number of tags should increase much more slowly. Thus, the apparent tag rate (N+/Njet) will decrease, although the actual tag rate (N+/Njet from highest P.V.) should not. I also have the number of z vertices, plus the average number of z vertices versus luminosity. ]]>     Updated Mistag Talk with some Mods 2004-06-30T18:59:07Z 2004-06-30T12:59:07-06:00 tag:harv11.fnal.gov,2004:/hlogs/SecVtx/5.171 2004-06-30T18:59:07Z Updated talk on mistags: Download file... rappocc rappoccio@huhepl.harvard.edu Mistags Download file]]> Rough Copy of BTagging Meeting Talk 2004-06-30T15:02:33Z 2004-06-30T09:02:33-06:00 tag:harv11.fnal.gov,2004:/hlogs/SecVtx/5.169 2004-06-30T15:02:33Z Rough copy of talk Joao should give for me at Friday's btagging meeting is here.
