Abstract
It is shown that high-energy multiplicity distributions can be described by multiple-Pomeranchuk-pole exchange if the Pomeranchuk pole is fixed. A proposed model provides a one-parameter formula for multiplicity distributions and the fit of this single parameter to the data gives the moments of the distribution and its large-multiplicity behavior in complete agreement with measured cross sections. Predictions concerning the average number of neutral particles as a function of the observed number of charged ones are also in agreement with the data. The model is still valid if the Pomeranchuk pole is moving but has a small slope. Corrections due to the nonvanishing slope of the Pomeranchuk trajectory are calculated. They are detectable by improving the statistics of measurements of multiplicity distributions.
