Estimates of cluster size in high-energy hadron collisions

Abstract
We discuss the parameterization of the strength of clustering effects in hadronic final states in terms of an average cluster size which is inferred from predictions of a cluster emission model. Particular attention is paid to the general question of sensitivity and the importance of assumptions regarding the kinematic constraints and statistical independence. Evidence that the cluster sizes are significantly larger than the decay multiplicities of the familiar low-mass resonances is found in a large range of experimental data.
