**************************************************************************** Calculations of bunching parameters characterizing 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.

public BunchingParameters(int NmaxOrder, int Bins, int step, double Min, double Max)
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 XMethod Detail |
