Fine tuning of track impact parameter resolution of the DELPHI detector

The fine tuning of the charged track impact parameter resolution for data and simulation in the DELPHI detector at LEP is described. This tuning was implemented in the software for the tagging of B hadrons and has been applied in many precise measurements.

electron positron: colliding beams
colliding beams: electron positron
B: electroproduction
electroproduction: B
B: lifetime
track data analysis: impact parameter
tracks: resolution
