Detailed Description

Analysis component for reconstructed tracks.

Track analysis component: Loops over tracks from the EMCal track container and counts the tracks in histograms. Separate histograms are filled for tracks which have an EMCAL cluster assigned, and the Monte-Carlo information in case the analysis is performed on Monte-Carlo events. In this case also the correlation matrix between reconstructed \( p_{t} \) and generated \( p_{t} \) is filled.

Member Function Documentation

void EMCalTriggerPtAnalysis::AliEMCalTriggerRecTrackAnalysisComponent::CreateHistos ( )
virtual

Creating histograms for the analysis component.

Create histograms of the track analysis component and add it to the list of histograms. For each trigger class we have

  • tracks with esd information
  • tracks with MC information
  • tracks with clusters and esd information
  • tracks with clusters and MC information In addition, a correlation matrix (THnSparse) for the correlation beween generated and reconstructed \( p_{t} \) is created.

This function is the implementation of the abstract method CreateHistos declared in AliEMCalTriggerTracksAnalysisComponent.

Reimplemented from EMCalTriggerPtAnalysis::AliEMCalTriggerTracksAnalysisComponent.

Fill main track-based histogram.

Fill main track-based histogram defined by its name with

  1. \( p_{t} \)
  2. \( \eta \)
  3. \( \phi \)
  4. z-position of the primary vertex
  5. status flag signalizing that the event was also a minimum bias event If useMCkine is set to true, the kinematic quantities will be obtained from the associated MC particle.
Parameters
histnameName of the THnSparse to fill
trkReconstructed track
assocMCThe associated MC track
recevReconstructed event
useMCkineIf true we fill histogram with MC truth information
weightEvent weight (optional)

Check whether track is a true signal track.

Check according to the associated MC information whether the track is a MC true track, and whether it is physical primary

Parameters

evntMC event information necessary for the check
Returns
the associated MC particle (NULL if not MC true)

void EMCalTriggerPtAnalysis::AliEMCalTriggerRecTrackAnalysisComponent::Process ( const AliEMCalTriggerEventData *const  data)
virtual

Run track loop on list of matching tracks.

Analyses all particles at reconstruction level in an event, and fill a track based histogram for all triggers which selected the event. Following steps are performed:

  1. Get a list of all triggers which selected the event
  2. Iterate over pre-selected tracks
    • Check kinematics and track selection cuts
    • Check whether the track is a true signal track (if MC information is available). If yes, fill correlation matrix
    • Fill histogram at track level (and if an associated particle is available also at MC-truth level)
    • Find cluster matched to track. If cluster is available, fill histograms for tracks with clusters
    • Find trigger patches mathced to track. If trigger patch is available, fill histogram for tracks with patches This function is the implementation of the abstract method Process declared in AliEMCalTriggerTracksAnalysisComponent.
Parameters
datathe event data
