Generalized Bunching Parameters and Multiplicity Fluctuations in   Restricted Phase-Space Bins
  Experimental aspects of the use of bunching parameters are discussed. Special attention is paid to the behavior expected for the case of purely statistical fluctuations. We studied bin-averaged bunching parameters and propose a generalization of bunching parameters, making use of the interparticle distance-measure technique. The proposed method opens up the possibility of carrying out a comprehensive and sensitive investigation of multiplicity fluctuations inside jets.
