Bose-Einstein or HBT correlations and the anomalous dimension of QCD

High Energy Physics - Phenomenology 2007-05-23 v1 Nuclear Theory

Abstract

Bose-Einstein (or HBT) correlation functions are evaluated for the fractal structure of QCD jets. These correlation functions have a stretched exponential (or Levy-stable) form. The anomalous dimension of QCD determines the Levy index of stability, thus the running coupling constant of QCD becomes measurable with the help of two-particle Bose-Einstein correlation functions. These considerations are tested on NA22 and UA1 two-pion correlation data.
