On Contributions of Two-Particle Correlation Functions to the Intermittent behavior in Heavy-Ion Collisions
Abdelnasser M. Tawfik
Abstract
The factorial moments (FM) of the multiplicity distributions in one- and two-dimensions are studied in Pb+Pb collisions at 158 AGeV. Obvious intermittency slopes are observed in the relation between FM and the partition number M. The Bose-Einstein correlations (BEC) are investigated in the emulsion data sample. The influences of the two-particle correlation functions (TPCF) on the scaling behavior of FM are also investigated. The dependence of TPCF on the invariant relative momentum Q as well as on the pseudo-rapidity δη are calculated. It is found that TPCF fulfill the requirements of a power-law scaling comparable with the scaling rule of FM. The expected contributions of TPCD to FM are quantitatively estimated.
