Soft hadronic production by ECCO in the geometrical branching model

Soft production of hadrons in hadronic collisions is described in the geometrical branching model and implemented by the eikonal cascade code (ecco). It is shown that the major global features of multiparticle production can be reproduced by one essential characterization of the dynamics of branching, namely, a scaling law for the mass distribution of daughter clusters. Without further adjustment of any parameters, the event generator can produce local features of multiplicity fluctuations in agreement with the NA22 intermittency data. The scaling exponent $\nu$ is determined to be 1.522 at $\sqrt{s}=22\mathrm{}$ GeV, independent of the dimensionality of the intermittency analysis. It is shown that $\nu$ is approximately independent of the collision energy.
