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

px	x-component of the momentum vector
py	y-component of the momentum vector
pz	z-component of the momentum vector
e	Particle energy
pdgcode	PDG 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

ref	Reference 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

trk	Reconstructed track matched to the particle

void HighPtTracks::AliReducedJetParticle::FillLorentzVector

(

TLorentzVector &

ref

)

const

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

Parameters

ref	The 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

itrk	Number 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

itrk	Index 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

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
