Analyses of multiplicity distributions by means of the Modi ed Negative Binomial Distribution and its KNO scaling function
We analyze various data of multiplicity distributions by means of the Modi ed Negative Binomial Distribution (MNBD) and its KNO scaling function, since this MNBD explains the oscillating behavior of the cumulant moment observed in ee annihilations, h-h collisions and e-p collisions. In the present analyses, we nd that the MNBD (discrete distributions) describes the data of charged particles in ...
متن کاملAnalyses of multiplicity distributions by means of the Modified Negative Binomial Distribution and its KNO scaling function
We analyze various data of multiplicity distributions by means of the Modified Negative Binomial Distribution (MNBD) and its KNO scaling function, since this MNBD explains the oscillating behavior of the cumulant moment observed in e+e− annihilations, h-h collisions and e-p collisions. In the present analyses, we find that the MNBD (discrete distributions) describes the data of charged particle...
متن کاملKNO scaling 30 years later
KNO scaling, i.e. the collapse of multiplicity distributions Pn onto a universal scaling curve manifests when Pn is expressed as the distribution of the standardized multiplicity (n− c)/λ with c and λ being location and scale parameters governed by leading particle effects and the growth of average multiplicity. At very high energies, strong violation of KNO scaling behavior is observed (pp̄) an...
متن کاملKNO scaling in processes of electron - positron annihilation to hadrons
The charged particles multiplicity distribution in the KNO form is discussed in processes of ee annihilation at energies √ s 14 – 206.2 GeV. The experimental data are compared to data, obtained with Monte Carlo simulation in PYTHIA in the Lund quark string model. It is shown, that both experimental and simulated data are described by the same distribution function in the KNO form. It is shown, ...
متن کاملKNO scaling function of modified negative binomial distribution
We investigate the KNO scaling function of the modified negative binomial distribution (MNBD), because this MNBD can explain the oscillating behaviors of the cumulant moment observed in e+e− annihilations and in hadronic collisions. By using a straightforward method and the Poisson transform we derive the KNO scaling function from the MNBD. The KNO form of experimental data in e+e− collisions a...
