  • Background and Data Summary Table, no HT requirement (.tex), (.png)

Njets (HT200) Njets (no HT)
Tagged background contributions and results from data as a function of event jet multiplicity, after the HT requirement has been applied to events with 3 or more jets. (gif), (eps) Tagged background contributions and results from data as a function of event jet multiplicity, without any HT requirement. (gif), (eps)

Njets (HT200) Njets (no HT)
Tagged background and t-tbar signal contributions and results from data as a function of event jet multiplicity, after the HT requirement has been applied to events with 3 or more jets. (gif), (eps) Tagged background and t-tbar signal contributions and results from data as a function of event jet multiplicity, without any HT requirement. (gif), (eps)

Good Tracks Vertex Mass
Number of tracks within the jet cone satisfying some quality criteria (a.k.a. "good tracks") in tagged jets for all backgrounds and data. (gif), (eps) Tagged jets vertex mass of the candidates, with expected t-tbar and background contributions. (gif), (eps)

Jet Et Vertex L2d
Tagged jets ET of the candidates, with expected t-tbar and background contributions. (gif), (eps) Tagged jets Lxy of the candidates, with expected t-tbar and background contributions. (gif), (eps)


HT (Candidates) HT (MC)
HT distribution of the tagged candidates (3 or more jets), with expected t-tbar and background contributions. (gif), (eps) HT distribution of expected t-tbar and background contributions. (jpg), (eps)
Vertex 155145 Lego 155145
Vertex display of double tags in run 155145, event 132579. (gif), (eps) Lego plot of run 155145, event 132579, with an electron plus 3 jets. (gif), (eps)

Vertex 167551 Lego 167551
Vertex display of double tags in run 167551, event 7969376. (gif), (eps) Lego plot of run 167551, event 7969376, with an electron plus 4 jets. (gif), (eps)

Z+Jets
Results from the SECVTX-tagged Z+jets selection (no HT requirement). Background is estimated from the positive tag rate of generic jet sample applied to the Z+jets pre-tag sample. (gif), (eps)
