public class BunchingParameters extends java.lang.Object
Calculations of bunching parameters. They haracterize local multiplicity fluctuations inside a phase space. Calculations are done up to BP(6) order For a Poisson distribution it should be 1 for all divisions Here are relevant papers:1) LOCAL MULTIPLICITY FLUCTUATIONS IN HADRONIC Z DECAY.

BunchingParameters
public BunchingParameters(int NmaxOrder, int Bins, int step, double Min, double Max)
Initialize Bunching parameter.- Parameters:
NmaxOrder
- Max order of the bunching parameter (starting from 2)!Bins
- Defines Max number of bins used to divide the phase space (>1). The actual number of divisions is step*Bins. Therefore, 10 bins with step=4 means 400 divisions between Min and Maxstep
- used to increase step for divisionsMin
- Min value in XMax
- Max value in X

run
public void run(double[] v)
Collect information about sampling. Put this method in a loop and pass vector with particle characteristics.- Parameters:
v
- - vector characterizing particles (like momentum, speed etc)
-
eval
public boolean eval()
Evaluate bunching parameters at the end of the run- Returns:
- true if success
-
getBP
public P1D getBP(int order)
Return results: BP as a function of number of bins. The order should be >1 but smaller than 8- Parameters:
order
- order of bunching parameter- Returns:
- bunching parameters
