Two Track Trigger Hadronic D°->Kpi
signal PR Plots
Last Update: Mar. 06th, 2003 06:10PM
The following PR plot is based on the TTT sample collected until now.
namely 65 pb-1 of the multibody path.
The preselection cuts applied to the sample are:
the B_CHARM trigger path is selected using prereq
"Bad runs: are excluded using B validation group TTT good runs
list
Common reconstruction techniques applied to all tracks in the event:
3 r-phi Silicon hits are required BEFORE refitting for D0
doughters tracks
Pt>2. GeV for D0 daughters tracks
|eta|<2
D0 tracks are matched with SVT tracks and Scenario "A" Trigger cuts
are applied on the SVT matched tracks.
The plot show the Kpi invariant mass distribution with superimposed the sum
of the 9 fitting functions
obtained fitting the invariant mass ditributions in 9 Pt(D0) bins from 5.5
to 70. GeV/c (The bin width is
variable).
