Multiplicity distributions in high-energy collisions derived from the statistical bootstrap model

Analysis of Cumulant Moments in High Energy Hadron-Hadron Collisions by Truncated Multiplicity Distributions

Oscillatory behavior of cumulant moments obtained from the experimental data in pp collisions and p̄p collisions are analyzed by the modified negative binomial distribution (MNBD) and the negative binomial distribution (NBD). Both distributions well describe the cumulant moments obtained from the data. This fact shows sharp contrast to the result in ee collisions, which is described by the the M...

Multiplicity Distribution and Mechanisms of the High-Energy Hadron Collisions

We discuss the multiplicity distribution for highest accessible energies of ppand p̄pinteractions from the point of view of the multiparton collisions. The inelastic cross sections for the single, σ1, and multiple (double and, presumably, triple, σ2+3) parton collisions are extracted from the analysis of the experimental data on the multiplicity distribution up to the Tevatron energies. It follo...

Interpreting Multiplicity-Gated Fragment Distributions from Heavy-Ion Collisions

Multiplicity distributions in rapidity for Pb-Pb and p-Pb central collisions from a simple model

In the String Percolation Model [1] the particle density is proportional, once the colour reduction factor is taken into account, to the average number of participants ρ ∝ NA; the normalized particle density at mid-rapidity is related to the gluon distribution at small Bjorken-x, ρ ∝ exp ; and the dense-dilute separation scale decreases, from energy conservation, linearly with Y , ∆0 = −αY with...

2 00 4 Scenarios for multiplicity distributions in pp collisions in the TeV energy region

Possible scenarios based on available experimental data and phenomenological knowledge of the GeV energy region are extended to the TeV energy region in the framework of the weighted superposition mechanism of soft and semi-hard events. KNO scaling violations, forward-backward multiplicity correlations, Hq vs. q oscillations and shoulder structures are discussed.
