Use case for flavour tagging calibration.

Outline of use case

The calibration of flavour tagging requires the analysis of a large number of channels of data. Some of them are potentially triggered in multiple ways like the semi-leptonic decays.

Selection

Issues

Number of streams from the detector

Pros and cons for this particular analysis for having one or more streams from the detector.

Information required on trigger, stripping and luminosity

Number of streams in the stripping

Pros and cons for this particular analysis of many/few streams.

Information stored for each event

For the large number of control samples used in the flavour tagging there would be an advantage of storing the B candidate that selected the event. In this way the subsequent flavour tagging could be performed in an analysis without concern about running all the selection algorithms again.

There could be a need for storing both flavour tag information and some event weight as well. -- UlrikEgede - 27 Jul 2006
