Critical Exponents and Particle Multiplicity Distributions in High Energy Collisions
arXiv:0711.4397 · doi:10.1016/j.nuclphysa.2008.06.008
Abstract
Data from the L3, Tasso, Opal and Delphi collaborations are analyzed in terms of a statistical model of high energy collisions. The model contains a power law critical exponent tau and Levy index alpha. These data are used to study values of tau and alpha. The very high multiplicity events in L3, Opal and Delphi are consistent with a model based on a Feynman-Wilson gas which has a tail exponent tau=3/2 and alpha=1/2.
