Description

The recently observed scaling property of entropy obtained from multiplicity distributions in high energy reactions is analyzed in quantum statistical terms. The role of non-diagonal elements of the density matrix is emphasized and illustrated in a two-component model, containing a chaotic and a coherent source. A new scaling property of the mean chaotic multiplicity as a function of rapidity and energy and a master equation for the chaotic multiplicity distribution are derived. (orig.)
