Detailed Description

Reduced information set of particles associated with a jet.

Object storing particle based information for tracks associated with jets. The object contains the 4-momentum vector of the particle, the PDG code, the distance to the main jet axis of its associated jet, the number of TPC track references of the Monte-Carlo true particle, and a list of reduced reconstructed tracks associated to the true particle.

Constructor & Destructor Documentation

HighPtTracks::AliReducedJetParticle::AliReducedJetParticle ( )

Dummy (I/O) constructor, not to be used

Definition at line 28 of file AliReducedJetParticle.cxx.

HighPtTracks::AliReducedJetParticle::AliReducedJetParticle ( double  px,
double  py,
double  pz,
double  e,
int  pdgcode 
)

Main constructor, initializes the particle with the moment vector, the particle energy and the PDG code. Also creates a container for tracks matched to the particle via the Monte-Carlo label, which takes ownership over the matched tracks.

Parameters
pxx-component of the momentum vector
pyy-component of the momentum vector
pzz-component of the momentum vector
eParticle energy
pdgcodePDG code of the particle

Definition at line 54 of file AliReducedJetParticle.cxx.

HighPtTracks::AliReducedJetParticle::AliReducedJetParticle ( const AliReducedJetParticle ref)

Copy constructor. For each matched track, a copy is created and stored in the new object.

Parameters
refReference for the copy

Definition at line 75 of file AliReducedJetParticle.cxx.

HighPtTracks::AliReducedJetParticle::~AliReducedJetParticle ( )
virtual

Destructor. Deletes all matched tracks associated to the particle.

Definition at line 121 of file AliReducedJetParticle.cxx.

Member Function Documentation

void HighPtTracks::AliReducedJetParticle::AddMatchedTrack ( AliReducedMatchedTrack trk)

Adds a new matched reconstructed track to the jet particle. Tracks are matched via the Monte-Carlo label.

Parameters
trkReconstructed track matched to the particle

Definition at line 141 of file AliReducedJetParticle.cxx.

Referenced by HighPtTracks::AliHighPtReconstructionEfficiency::ProcessJet().

void HighPtTracks::AliReducedJetParticle::FillLorentzVector ( TLorentzVector &  ref) const

Access to the particle kinematics information via a TLorentzVector which is filled inside the function

Parameters
refThe TLorentzVector to be filled

Definition at line 131 of file AliReducedJetParticle.cxx.

double HighPtTracks::AliReducedJetParticle::GetDeltaPt ( int  itrk = 0) const

Calculate the difference between reconstructed and generated \( p_{t} \) relative to the generated \( p_{t} \) . If no matching track is found for the index, returns -1000.

Parameters
itrkNumber of the matched track to be checked (0 as default)
Returns
\((p_{t,gen} - p_{t,rec})/p_{t,rec}\) (-1000 if no track is available)

Definition at line 152 of file AliReducedJetParticle.cxx.

double HighPtTracks::AliReducedJetParticle::GetDistanceToJetMainAxis ( ) const
inline

Get distance to the main jet axis.

Returns
The reconstructed distance

Definition at line 59 of file AliReducedJetParticle.h.

AliReducedMatchedTrack* HighPtTracks::AliReducedJetParticle::GetMatchedTrack ( int  itrk)
inline

Get matched track with given index. In case the index is out of bounds, return a nullpointer.

Parameters
itrkIndex to check
Returns
The track with this index (NULL if out of bounds)

TObjArray* HighPtTracks::AliReducedJetParticle::GetMatchedTracks ( ) const
inline

Definition at line 92 of file AliReducedJetParticle.h.

int HighPtTracks::AliReducedJetParticle::GetNumberOfMatchedTracks ( ) const
inline

Get the number of matched reconstruced tracks associated to the particle.

Returns
Number of matched reconstructed tracks

Definition at line 81 of file AliReducedJetParticle.h.

unsigned short HighPtTracks::AliReducedJetParticle::GetNumberOfTPCTrackReferences ( ) const
inline

Get the number of track references in the TPC for the particle

Returns
The number of TPC track references

Definition at line 90 of file AliReducedJetParticle.h.

int HighPtTracks::AliReducedJetParticle::GetPdgCode ( ) const
inline

Get the PDG code of the particle.

Returns
The PDF code

Definition at line 66 of file AliReducedJetParticle.h.

bool HighPtTracks::AliReducedJetParticle::IsReconstructed ( ) const
inline

Checks if the track is reconstructed. Reconstructed tracks are defined as tracks with at least one associated track.

Returns
True if at least one reconstructed track is found, false otherwise

Definition at line 74 of file AliReducedJetParticle.h.

AliReducedJetParticle & HighPtTracks::AliReducedJetParticle::operator= ( const AliReducedJetParticle ref)
