Multiplicity distributions associated to subthreshold events in heavy-ion collisions

Subthreshold events (pion production, for instance) at energies E < mπ are treated as rare events. The associated multiplicity distribution Pc(n) and the unconstrained distribution P (n), when there is no rare event-trigger, are related by the model independent relation Pc(n) = n2 〈n2〉 (n) . This relation, and in particular its improved version inspired in clustering of nucleons, is in fair agr...

Multiplicity Distributions in Strong Interactions: a Generalized Negative Binomial Model

A three-parameter discrete distribution is developed to describe the multiplicity distributions observed in totaland limited phase space volumes in different collision processes. The probability law is obtained by the Poisson transform of the KNO scaling function derived in Polyakov’s similarity hypothesis for strong interactions as well as in perturbative QCD, ψ(z) ∝ zα exp(−zμ). Various chara...

A Bose-Einstein Model of Particle Multiplicity Distributions

A model of particle production is developed based on a parallel with a theory of Bose-Einstein condensation and similarities with other critical phenomena such as critical opalescence. The role of a power law critical exponentτ and Levy indexα are studied. Various features of this model are developed and compared with other commonly used models of particle production which are shown to differ b...

Diffractive parton distributions in light - cone QCD ∗

We discuss recent theoretical results on diffractive deeply inelastic scattering, focusing on the partonic picture of diffraction in configuration space and the predictions for the β behavior and the scaling violation. Typeset using REVTEX Talk by F. Hautmann at the International Symposium on Multiparticle Dynamics and QCD ISMD99, Brown University, 9-13 August 1999, to appear in the proceedings.
