[en] Recent experiments on small-p_T hadron production in pp collisions have shed new light on the apparent violation of the universality ansatz that the multiplicity dispersion in hadron-hadron collisions is much larger than that in e⁺e^- collisions. We present a model based on the universality ansatz, among other things. This model reproduces qualitatively the hadron multiplicity distributions in pp collisions over a wide range of energies. Within our framework, this essentially resolves the discrepancy stated above. In our approach the universality ansatz is also found to be applicable to the diffractive component events. This is supported by the inclusive x-distribution data having various specified number of prongs in the final states
