Detailed Description

Class that contains the forward multiplicity data per event

This class contains a histogram of

\[ \frac{d^2N_{ch}}{d\eta d\phi}\quad, \]

as well as a trigger mask for each analysed event.

The eta acceptance of the event is stored in the underflow bins of the histogram. So to build the final histogram, one needs to correct for this acceptance (properly weighted by the events), and the vertex efficiency. This simply boils down to defining a 2D histogram and summing the event histograms in that histogram. One should of course also do proper book-keeping of the accepted event.

TTree* GetAODTree()
{ 
   TFile* file = TFile::Open("AliAODs.root","READ");
   TTree* tree = static_cast<TTree*>(file->Get("aodTree"));
   return tree;
}
void Analyse()
{ 
  TH2D*              sum        = 0;                  // Summed hist
  TTree*             tree       = GetAODTree();       // AOD tree
  AliAODForwardMult* mult       = 0;                  // AOD object
  Int_t              nTriggered = 0;                  // # of triggered ev.
  Int_t              nWithVertex= 0;                  // # of ev. w/vertex
  Int_t              nAccepted  = 0;                  // # of ev. used
  Int_t              nAvailable = tree->GetEntries(); // How many entries
  Float_t            vzLow      = -10;                // Lower ip cut
  Float_t            vzHigh     =  10;                // Upper ip cut
  Int_t              mask       = AliAODForwardMult::kInel;// Trigger mask
  tree->SetBranchAddress("forward", &forward);        // Set the address
  for (int i = 0; i < nAvailable; i++) { 
    // Create sum histogram on first event - to match binning to input
    if (!sum) sum = static_cast<TH2D*>(mult->Clone("d2ndetadphi"));
    tree->GetEntry(i);
    // Other trigger/event requirements could be defined 
    if (!mult->IsTriggerBits(mask)) continue; 
    nTriggered++;
    // Check if we have vertex 
    if (!mult->HasIpZ()) continue;
    nWithVertex++;
    // Select vertex range (in centimeters) 
    if (!mult->InRange(vzLow, vzHigh) continue; 
    nAccepted++;
    // Add contribution from this event
    sum->Add(&(mult->GetHistogram()));
  }
  // Get acceptance normalisation from underflow bins 
  TH1D* norm   = sum->ProjectionX("norm", 0, 1, "");
  // Project onto eta axis - _ignoring_underflow_bins_!
  TH1D* dndeta = sum->Projection("dndeta", 1, -1, "e");
  // Normalize to the acceptance 
  dndeta->Divide(norm);
  // Scale by the vertex efficiency 
  dndeta->Scale(Double_t(nWithVertex)/nTriggered, "width");
  // And draw the result
  dndeta->Draw();
}

The above code will draw the final \( dN_{ch}/d\eta\) for the selected event class and vertex range

The histogram can be used as input for other kinds of analysis too, like flow, event-plane, centrality, and so on.

Bool_t AliAODForwardMult::CheckEvent	(	UInt_t	triggerMask = `kInel`,
		Double_t	vzMin = `-10`,
		Double_t	vzMax = `10`,
		Double_t	cMin = `0`,
		Double_t	cMax = `100`,
		TH1 *	hist = `0`,
		TH1 *	status = `0`,
		UInt_t	filterMask = `kDefaultFilter`
	)		const

Check if event meets the passses requirements.

It returns true if all of the following is true

The trigger is within the bit mask passed.
The vertex is within the specified limits.
The centrality is within the specified limits, or if lower limit is equal to or larger than the upper limit.

Note, for data with out a centrality estimate (e.g., pp), one must pass equal centrality cuts, or no data will be accepted. In other words, for pp data, always pass cMin=0, cMax=0

If a histogram is passed in the last parameter, then that histogram is filled with the trigger bits.

Parameters

triggerMask	Trigger mask. All bits in this mask must be set (AND)
vzMin	Minimum \( v_z\) (in centimeters)
vzMax	Maximum \( v_z\) (in centimeters)
cMin	Minimum centrality (in percent)
cMax	Maximum centrality (in percent)
hist	Histogram to fill
status	Histogram to fill
filterMask	Mask of trigger bits to filter on. If any bit in this mask is set, reject the event (OR)

Returns: true if the event meets the requirements
