Definition at line 36 of file AliAnalysisTaskJetUE.h.

Constructor & Destructor Documentation

AliAnalysisTaskJetUE::AliAnalysisTaskJetUE ( )

Default constructor. Needed by ROOT I/O

Definition at line 42 of file AliAnalysisTaskJetUE.cxx.

AliAnalysisTaskJetUE::AliAnalysisTaskJetUE	(	const char *	name,
		Bool_t	histo = `kFALSE`
	)

Standard constructor. Should be used by the user.

Parameters

[in]	name	Name of the task

Member Function Documentation

Bool_t AliAnalysisTaskJetUE::AreJetsOverlapping	(	AliEmcalJet *	jet1,
		AliEmcalJet *	jet2
	)

protected

Verify whether two jets have any track in common.

Parameters

jet1	First jet
jet2	Second jet

Returns: kTRUE if the two jets have at least a track in common, kFALSE otherwise

void AliAnalysisTaskJetUE::CalculateEventProperties ( )

protectedvirtual

Calculates event properties such as number of tracks, cluster, jets, leading track, cluster, jets etc.

Bool_t AliAnalysisTaskJetUE::IsB2BEvent ( std::string jetCollName = "Signal" )

protected

Determines whether the current event is a "back-to-back" event, using the following definition. An event is back-to-back if: 1) The event contains a jet whose azimuthal angle difference with the leading jet is > 5/6 pi (the "back-to-back" jet), and 2) the back-to-back jet carries a minimum fraction (fBackToBackJetPtFraction) of the leading jet momentum, and 3) there are no jets with momentum greater than a given threshold (fMaxMomentumThridJet) that have an azimuthal angle difference smaller than 5/6 pi with the leading jet.

Parameters

jetCollName name of the jet collection used to establish the back-to-back nature of the event
