Soft muons variables for tracks

Michele D'Andrea requested to merge midandre/athena:softMuons_track into main

Description

This merge request follows the discussion initiated in the related JIRA ticket AFT-708 regarding the addition of certain variables to muon tracks concerning SoftMuonTagging.

The changes were made exclusively in the TrackLeptonDecoratorAlg package of the JetTagging/FlavorTagDiscriminants tool.

These modifications involve adding specific decorators to the tracks to characterize muons with the following variables:

  • muon_quality: Integer variable describing the working point (WP) used for muon reconstruction. (0=Tight, 1=Medium, 2=Loose, 3=Veryloose, 4=HighPt, 5=LowPtEfficiency, -1=Default)

  • muon_qOverPratio: Variable representing the ratio between qOverP measured in the Inner Detector (ID) and that in the Muon Spectrometer (MS).

  • muon_momentumBalanceSignificance: Significance of the momentum balance between the ID and MS.

  • muon_scatteringNeighbourSignificance: Significance of the azimuthal angular difference between the two half tracks ending/starting at each of adjacent hits along the track.

For the last three variables the default value for non-muon tracks is set to nan.
