Detailed Description

Class for a task that calculates the UE.

Class for a task that calculates the average background coming from the underlying event (UE) in jet analysis. In each event, tha task finds the leading jet and sum the particle pT in a cone of R = 0.4 perpendicular to the leading jet axis. In addition another histogram is filled with the UE estimated in events that fulfill the back-to-back condition: a back-to-back jet, satisfying |∆φ| > 5/6π and carrying at least a given fraction (default: 60%) of the transverse momentum of the leading jet, is required to be present in the event. Additionally, all the other jets in the event should have pT smaller than a certain threshold (default: 12 GeV/c). This implements the techniques described in the analysis note of the ALICE inclusive jet spectrum in pp collisions at 2.76 TeV, section 7.3: https://aliceinfo.cern.ch/Notes/sites/aliceinfo.cern.ch.Notes/files/notes/analysis/rma/2013-Mar-29-analysis_note-ppJet_note.pdf If scale function is given the scaled rho will be exported with the name as "fOutRhoName".Apppend("_Scaled").

void AliAnalysisTaskRhoTransDev::CalculateRho ( )
protectedvirtual

Calculates the average background by summing the transverse momenta of the particles perpendicular to the leading jet axis. This implements the techniques described in the analysis note of the ALICE inclusive jet spectrum in pp collisions at 2.76 TeV, section 7.3: https://aliceinfo.cern.ch/Notes/sites/aliceinfo.cern.ch.Notes/files/notes/analysis/rma/2013-Mar-29-analysis_note-ppJet_note.pdf The background densisty is stored in fOutRho.

Double_t AliAnalysisTaskRhoTransDev::GetPerpPtDensity ( AliEmcalContainer *  cont,
AliVParticle *  leadingJet 
)
protected

Calculates the transervse momentum density in a region that is perpedincular to the leading jet. The perpedincular region spans over an angle pi/4 around pi/4 and -pi/4. This implements the techniques described in the analysis note of the ALICE inclusive jet spectrum in pp collisions at 2.76 TeV, section 7.3: https://aliceinfo.cern.ch/Notes/sites/aliceinfo.cern.ch.Notes/files/notes/analysis/rma/2013-Mar-29-analysis_note-ppJet_note.pdf

Parameters
contCollection of objects (tracks, clusters or particles) used to calculate the momentum density
leadingJetLeading jet used to define the perpendicular region
Returns
The perpendicular momentum density

Bool_t AliAnalysisTaskRhoTransDev::IsB2BEvent ( )
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.

Returns
A boolean indicating whether the event is classified as back-to-back (true) or not (false).
