Scale-Invariant Dynamical Fluctuations in Jet Physics

Abstract

An interpretation of scale-invariant multiplicity fluctuations inside hadronic jets is presented. It is based on the branching mechanism with the angular ordering of soft partons in sequential branchings. A relationship with fractal distributions is demonstrated. The model takes into account the finiteness of the number of particles produced in jets (finite energy) and leads to a good description of the multifractal fluctuations observed in E+E- processes.
