Detailed Description

Base class for a task that studies the UE.

Base class for tasks used to study the underlying event (UE) in jet analysis.

Implementation of a task used to study the underlying event in jet analysis.

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]nameName of the task
[in]histoIf kTRUE, the task will also produce QA histograms

Member Function Documentation

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

Verify whether two jets have any track in common.

Parameters
jet1First jet
jet2Second 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
jetCollNamename of the jet collection used to establish the back-to-back nature of the event
Returns
A boolean indicating whether the event is classified as back-to-back (true) or not (false).
