Member Enumeration Documentation

enum PWGJE::EMCALJetTasks::AliAnalysisTaskEmcalJetHUtils::ELeadingHadronBiasType_t

Determine the jet leading hadron bias type.

Enumerator
kCharged	! Charged hadron bias
kNeutral	! Neutral hadron bias
kBoth	! Leading is from the leader of both

Member Function Documentation

double AliAnalysisTaskEmcalJetHUtils::GetLeadingHadronPt ( AliEmcalJet *  jet, AliAnalysisTaskEmcalJetHUtils::ELeadingHadronBiasType_t  leadingHadronType  )

static

Determine leading hadron pt in a jet. This is inspired by AliJetContainer::GetLeadingHadronMomentum(), but that particular function is avoided because the cluster energy retrieved is always the raw E while the cluster energy used in creating the jet would be preferred. One could create a cluster container and go through all of those steps, but there is a simpler approach: the leading charged and neutral momenta are stored in AliEmcalJet while performing jet finding.

Parameters

[in]	jet	Jet from which the leading hadron pt should be extracted
[in]	leadingHadronType	Type of leading hadron pt to retrieve

Returns

Value of the leading hadron pt

double AliAnalysisTaskEmcalJetHUtils::RelativeEPAngle ( double  jetAngle, double  epAngle  )

static

Function to calculate angle between jet and EP in the 1st quadrant (0,Pi/2). Adapted from AliAnalysisTaskEmcalJetHadEPpid.

Parameters

jetAngle	Phi angle of the jet (could be any particle)
epAngle	Event plane angle

Returns

Angle between jet and EP in the 1st quadrant (0,Pi/2)
