Hadronic multiplicity distributions: example of a universal stochastic process.


The existence of approximate scaling of hadronic charged multiplicity distributions when plotted in KNO form (i.e., anti n P/sub n/ vs. n/anti n) continues to attract interest. Both the existence of the phenomenon, and the shape of the scaling curve psi (n/anti n) = anti n P/sub n/ (large n, anti n) has been explained from many geometrical-dynamical points of view. Here we propose instead that these results depend on a generic framework independent of dynamical details, which context moreover occurs in many areas of science. This view imposes global constraints on any modelistic view which must be respected as are the symmetries of a theory. What one learns from the existence of scaling and the form of psi is indeed interesting but different from traditional views. Carruthers,-P.
