Skewness And Kurtosis

Multiplicity distributions for e+e−→ hadrons recently reported by the AMY and DELPHI collaborations are compared with the data obtained at lower energies. It is proven that the new data obey the KNO-G scaling and the scaling function can be described by the lognormal distribution. The dispersions are linear functions of the mean as for the data measured at lower energies and the standardized moments (such as skewness and kurtosis) are independent of the energy. The energy dependence of the average multiplicity is described by <nch>=β sα−1.

The Scaling Function

It has been observed that the e+e− multiplicity distributions exhibit the following properties: the dispersions are linear functions of the mean and the distributions obey the KNO-G scaling with the scaling function of the lognormal shape. In this paper the scale invariant branching is assumed as a mechanism within which all these properties could be derived. It is shown that the lognormal shape of the scaling function can be obtained within proposed mechanism by using the generalization of the Central Limit Theorem. The dependence of the average multiplicity on energy is also derived within the postulated framework. It is also shown that many other phenomena encountered in nature have the similar statistical properties.

Overlap Model

The fragmentation parameters and interaction mean free paths for VH- and H-type cosmic-ray nuclei have been measured as functions of energy in nuclear emulsions. It is found that they are essentially independent of energy over the range from 100 MeV/n to 30 GeV/n. The mean free paths of the secondary nuclei produced in observed interactions also have been measured. With two major exceptions, the values of the mean free paths are found to be consistent with an overlap model for nuclear interactions. The value obtained for the secondary L-type nuclei appears to be significantly shorter than that expected from the model calculations, while that for the primary VH nuclei appears to be significantly longer.

The experimental results on the multiplicity and probability distribution of the emitted charged pions [Formula: see text] in the interactions of [Formula: see text]Kr[Formula: see text] projectile at around 1[Formula: see text]GeV per nucleon with nuclear emulsion targets are reported. In this work, we have employed a wounded nucleon model (WNM) to calculate the total number of wounded nucleons [Formula: see text] and the total number of interactions [Formula: see text]. The dependence of average multiplicities of produced relativistic charged particles on the calculated wounded nucleons and total interactions are investigated. The obtained results revealed that the average multiplicity of [Formula: see text] is dependent on the projectile and target mass number. The calculated values of the total number of wounded nucleons and the total numbers of interactions show a strong dependence on the mass of the colliding nuclei. The emission rate of the mean multiplicity of [Formula: see text] and [Formula: see text] linearly increases with increasing the total number of wounded nucleons and interactions.
