Purpose
Implement MC-truth / generated secondary vertex quantities for the triplet observables used in the B → J/ψ K analysis.
Changes
PWGDQ/Core/VarManager.h
Computes MC-truth decay length as the difference between collision.mcPosX() and track.vx() (daughter’s generated vertex = secondary vertex).
PWGDQ/Tasks/dqEfficiency_withAssoc.cxx
In AnalysisDileptonTrack::runDileptonHadron:
PWGDQ/Core/VarManager.cxx
Units defined for the corresponding new values.
PWGDQ/Core/HistogramsLibrary.cxx
Added MC-truth histogram class in the dilepton-trackf subgroup for plotting the new quantities.
