Dual-Resonance Model and Multiple Production
  The very high multiplicity (VHM) processes are considered to investigate consequences of the dual resonance models reach (exponential) mass spectrum. The virial decomposition is developed for description of the produced particles short-rang (resonance) correlations. It is shown that the reach mass spectrum is able to do more flat the VHM distribution: $\s_n=O(e^{-n})$ up to multiplicities $n\simeq\bar{n}^2$, $\bar{n}$ is the mean multiplicity. But for $n>>\bar{n}^2$ one should expect $\s_n<O(e^{-n})$.
