Bunching Parameter and Intermittency in High-Energy Collisions
S. V. Chekanov, V. I. Kuvshinov
Abstract
We introduce the parameter of bunching for an analysis of the intermittent structure of multihadron production in high-energy collisions following an analogy with photon counting in quantum optics. A power-law singularity is shown to exist for second-order bunching parameters in small phase-space intervals for the case of a monofractal structure of the multiplicity distribution and a similar form for the high-order parameters for the case of multifractality. The approximation of the high-order bunching parameters by the second-order provides a good description of the anomalous fractal dimensions for a number of experimental data with multifractal behavior.
