muVertexCode
Updated on Fri, 2009-11-20 14:26. Originally created by bouchet on 2009-06-01 13:12.
It is filled as a 3-Vector so that one can access to the transverse and z components

- 06/02 : parent_dca from event vertex and decay length.
PDF is here
- 06/15 : dEdx cut
- 06/16 : comparison of sigma_dca filled in MuKpi.
- 06/25 : pt from global tracks, helix and DcaGeometry
- 06/29 : comparison of trackDca and decayLength with different helices calculations
- 07/01 : plots for Spiros (ratio,difference pT from Globals and DcaGeometry) + plots GEANT (decayLength)
- 07/02 : investigation of THelixTrack failure
- 07/03 : update + correction
- 07/05 : pulls
plot of pulls and the sigma (assuming gaussian distribution) associated vs .1/pT
(for pions candidates, q=-1, SiliconHits>0)
The sigma of the pull is not exactly 1 ; to investigate = make some tracks quality cuts
- 07/06 : update on pulls
- 07/10 : comparison btw Production2 and MinBias (NTracks, ZVertex, # of vertices per event)
- 07/16 : comparison btw Minbias data and Production2
- 07/19 : correction for THelixTrack
- 07/19 : primary vertex resolution for MinBias and Prod2 data
- 07/25 : test of D^{0} embedding in AuAu hij
- 07/26 : update on the primary vertex resolution and for the test of D^{0} embedding with HIJING
prim Vertex Res. and D0 test
plot for the DCA resolution of tracks with Si hits with a cut on the primary vertex resolution (> 50 microns and <50 microns in XY) :
- 08/02
dca plots using old definition and using StDcaGeometry : ppt or pdf
updated plots : pdf
- 08/11 : DCA cut
- 08/16 : double counting :
- 09/02 : recent work : dcaTrack/decay and displaced vertices
- TCFIT (on D0 and K0s) :here
- D0 : here
- K0 : here
