Sub-Poissonian distribution in hadronic processes

We have formulated a sub-Poissonian representation for a special class of hadronic multiplicity distributions at high energy. This representation chooses a two-quanta generalization of the coherent state and can be used together with partially coherent and supercluster distributions. The Koba, Nielsen, and Olesen scaling is analyzed in detail. We demonstrate that the hadronic distributions for the high-mass diffractive processes, the individual $n_{+}$ ($n_{\mathrm{-}}$) of the ν- (ν¯-) induced processes, and the individual $n_{+}$ ($n_{\mathrm{-}}$) of the $e^{+}$ $e^{\mathrm{-}}$ collisions are all sub-Poissonian. They can be represented reasonably by the two-quanta coherent-state representation. Implication for the global-charge compensation for a restricted rapidity window is also discussed.
