Offline Vertex Reconstruction

Miscellaneous Plots

These plots (evt1, evt2, evt3) show simulated SMT hits for some typical ttbar events at D0.

This plot shows how well we can match reconstructed tracks to simulated tracks, in eta,phi space.

This plot compares matching of a reco track to the closest (left plots) and to the second closest (right plots) simulated track (Z into ee events)

This plot shows the transverse momentum resolution for reconstructed tracks in D0 (Z into ee events).

Distributions for number of generated tracks (Z into ee events)

This plot compares generated and reconstructed primary vertex position (Z into ee events)

Efficiency of primary vertex reconstruction as a function of the number of reconstructed tracks coming from the generated primary vertex (Z into ee events)

This plot shows the transverse and longitudinal spatial resolutions of the reconstructed primary vertex.

This plot shows typical spectra for "golden charged particles" in ttbar events. It also defines a "golden track": Pt > 0.5 GeV and |eta| < 1.6 (ttbar events)

This plot shows typical spectra for charged particles in ttbar events

Efficiency of primary vertex reconstruction in ttbar events

This plot shows the spatial resolutions (transversal and longitudinal) of reconstructed primary vertices for ttbar events.
