Technical details for the charged particle analysis in pp, p-Pb and Pb-Pb as a function of multiplicity and pT

How to use

  • AddTask macro: PWGCF/EBYE/macros/AddTaskBalancePsiCentralityTrain.C
    • Example (how to add balance function code for centrality 0-80% for charged particles with 0.2 GeV/c<pT<20.0 GeV/c and -0.8<eta<0.8 [Filter Bit 272, Centrality estimator "V0M", with two-track cut, w/o delta pT cut, with 3 sigma electron rejection]):
            gROOT->LoadMacro("$ALICE_PHYSICS/PWGCF/EBYE/macros/AddTaskBalancePsiCentralityTrain.C"); 
            AliAnalysisTaskBFPsi *task = AddTaskBalancePsiCentralityTrain(0, 80, kFALSE, kTRUE,kFALSE, "V0M", 10, -1, -1, 0.2, 20.0, -0.8, 0.8, -1, -1, kFALSE, kFALSE, kTRUE, 0.02,kFALSE,0.04, kFALSE,0.1,272, kTRUE, "AnalysisResults","","Centrality","AOD",kTRUE,3.,kTRUE,"",-1,0x0);  
            

  • Macro to obtain correlation functions: PWGCF/EBYE/macros/drawCorrelationFunctionPsi.C
    • Example (correlation function histograms for centrality 0-5% for 0.2 GeV/c<pT,assoc<pT,trig<2.0 GeV/c [Filter Bit 272, Centrality estimator "V0M"]):
            aliroot 
            .L drawCorrelationFunctionPsi.C
            drawCorrelationFunctionPsi("AnalysisResults.root",1,272,"V0M",0,1,0.,5.,-10,10,0.2,2.0,0.2,2.0,1,1.*TMath::Pi()/6,1,1,1,"Centrality",0,"")
            

  • Macro to obtain balance function: PWGCF/EBYE/macros/drawBalanceFunction2DPsi.C
    • Example (balance function histogram for centrality 0-5% for 0.2 GeV/c<pT,assoc<pT,trig<2.0 GeV/c):
            aliroot 
            .L drawBalanceFunction2DPsi.C
            drawBFPsi2DFromCorrelationFunctions("",-1,"",-1,"",1,0.,5.,-10,10,0.2,2.0,0.2,2.0,"Centrality",kTRUE,kFALSE,kFALSE)
