Detailed Description

General jet finder task implementing a wrapper for FastJet.

Author: Constantin Lozides cloiz.nosp@m.ides.nosp@m.@lbl..nosp@m.gov, Lawrence Berkeley National Laboratory; Marta Verweij; Salvatore Aiola salva.nosp@m.tore.nosp@m..aiol.nosp@m.a@ce.nosp@m.rn.ch, Yale University

This class implements a wrapper for the FastJet jet finder. It allows to set a jet definition (jet algorithm, recombination scheme) and the list of jet constituents. Jet constituents are provided via multiple instances of AliParticleContainer and AliClusterContainer. These classes are delegated for applying cuts and filtering constituents that are then fed to the jet finder. This task will further filter constituents based on whether the jet was defined as being charged, neutral or full. The jet finding is delegated to the class AliFJWrapper which implements an interface to FastJet.

The FastJet contrib utilities are available via the AliEmcalJetUtility base class and its derived classes. Utilities can be added via the AddUtility(AliEmcalJetUtility*) method. All the utilities added in the list will be executed. Users can implement new utilities deriving a new class from AliEmcalJetUtility to interface functionalities of the FastJet contribs.

Member Function Documentation

AliEmcalJetUtility * AliEmcalJetTask::AddUtility ( AliEmcalJetUtility * utility )

Add a utility to the utility list. Utilities are instances of classes derived from AliEmcalJetUtility that implements wrappers to FastJet contribs.

Definition at line 122 of file AliEmcalJetTask.cxx.

fastjet::JetAlgorithm AliEmcalJetTask::ConvertToFJAlgo ( EJetAlgo_t algo )

static

Converts the internal enum values representing jet algorithms in the corresponding values accepted by the FastJet wrapper.

Parameters

algo	Algorithm represented in the EJetAlgo_t enum

Returns: Algortithm represented in the fastjet::JetAlgorithm enum

fastjet::RecombinationScheme AliEmcalJetTask::ConvertToFJRecoScheme ( ERecoScheme_t reco )

static

Converts the internal enum values representing jet recombination schemes in the corresponding values accepted by the FastJet wrapper.

Parameters

reco	Recombination scheme represented in the EJetAlgo_t enum

Returns: Recombination scheme represented in the fastjet::JetAlgorithm enum

void AliEmcalJetTask::ExecOnce ( )

protectedvirtual

This method is called once before analzying the first event. It generates the output jet branch name, initializes the FastJet wrapper and the utilities (FJ contribs).

Reimplemented from AliAnalysisTaskEmcal.

Definition at line 347 of file AliEmcalJetTask.cxx.

void AliEmcalJetTask::ExecuteUtilities	(	AliEmcalJet *	jet,
		Int_t	ij
	)

protected

This method is called in the event loop for each jet found, while filling the output jet branch. It executes the ProcessJet() method of all utilities (if any).

Definition at line 162 of file AliEmcalJetTask.cxx.

Referenced by FillJetBranch().

void AliEmcalJetTask::FillJetBranch ( )

protected

This method fills the jet output branch (TClonesArray) with the jet found by the FastJet wrapper. Before filling the jet branch, the utilities are prepared. Then the utilities are called for each jet and finally after jet finding the terminate method of all utilities is called.

		std::vector< fastjet::PseudoJet > &	constituents_unsub,
		Int_t	flag = `0`,
		TClonesArray *	particles_sub = `0`
	)

This method is called for each jet. It loops over the jet constituents and adds them to the jet object.

Parameters

jet	Pointer to the AliEmcalJet object where the jet constituents will be added
constituents	List of the jet constituents returned by the FastJet wrapper
constituents_unsub	List of jet constituents before background subtraction
flag	If kTRUE it means that the argument "constituents" is a list of subtracted constituents
particles_sub	Array containing subtracted constituents

Finds which geometrical acceptance types the jet satisfies.

Returns: bitwise jet acceptance type

Referenced by FillJetBranch().

Int_t AliEmcalJetTask::FindJets ( )

protected

This method steers the jet finding. It first loops over all particle and cluster containers that were provided when the task was initialized. All accepted objects (tracks, particle, clusters) are added as input vectors to the FastJet wrapper. Then the jet finding is launched in the wrapper.

Returns: Total number of jets found.

Bool_t AliEmcalJetTask::IsLocked ( ) const

An instance of this class can be "locked". Once locked, it cannot be unlocked. If the instance is locked, attempting to change the configuration will throw a fatal and stop the execution of the program. This method checks whether the instance is locked and throw a fatal if it is locked.

void AliEmcalJetTask::SelectCollisionCandidates ( UInt_t offlineTriggerMask = AliVEvent::kMB )

This overloads the method of AliAnalysisTaskSE to set the trigger bits. Since the output of this task is often a shared input of several consumer task the event selection is not allwed.

Parameters

offlineTriggerMask Trigger bit mask
