Nucleus-nucleus collisions at high energies

M. K. Hegab; M. T. Hussein; N. M. Hassan

Nucleus-nucleus collisions are studied in the framework of an extended Glauber model in which terms higher than the first (optical limit) in the phase shift expansion are considered. These are the so-called eclipse correction terms. The inelastic cross sections and distributions with respect to both the number of interacting nucleons and protons are calculated for various nucleus-nucleus interactions. The results show satisfactory agreement with the available experimental data.

Multiplicity distributions produced in high-energy nucleus-nucleus collisions

M. K. Hegab; Mohamed Tarek Hussein; N. M. Hassan

Two models are proposed to study the multiplicity distribution of negative particles produced in nucleus-nucleus interactions. The inelastic total and partial cross sections of AA collisions, in which eclipse corrections are considered, are used as basic inputs of the present calculations. The dependence of the average multiplicity on the mass number of the interacting nuclei is also investigated via the two models and the results are compared with recent data ranging from the several GeV region up to the very high CERN ISR data.

Asymmetry in high-energy hadron-hadron collisions

M. T. Hussein; N. M. Hassan; A. Rabea

SummaryThe asymmetry in hadron-hadron interactions is studied in the frame of a proposed multiperipheral model, where inclusive particle distributions are reproduced by the Monte Carlo technique. The dependence of the asymmetry upon the incident energy and the interacting particles is explained in view of the hadron-hadron quark structure. Calculations are compared with data of πp and pp at 50, 100 and 200 GeV incident hadron energy.

HADRON PRODUCTION IN NEUTRINO–NUCLEON INTERACTIONS AT HIGH ENERGIES

M. T. Hussein; N. M. Hassan; W. Elharbi

The multi-particle productions in neutrino–nucleon collisions at high energy are investigated through the analysis of the data of the experiment CERN-WA-025 at neutrino energy less than 260 GeV and the experiments FNAL-616 and FNAL-701 at energy range 120–250 GeV. The general features of these experiments are used as base to build a hypothetical model that views the reaction through a Feynman diagram of two vertices. The first of which concerns the weak interaction between the neutrino and the quark constituents of the nucleon. At the second vertex, a strong color field is assumed to play the role of particle production, which depend on the momentum transferred from the first vertex. The wave functions of the nucleon constituent quarks are determined using the variation method and relevant boundary conditions are applied to calculate the deep inelastic cross sections of the virtual diagram.

Clustering phenomena in high energy Hadron-nucleus interactions

M. T. Hussein; M. K. Hegab; N. M. Hassan

A hypothetical model based on the production of two clusters in hadronnucleus collisions is proposed. The identification of the produced clusters depends mainly on the analysis of the experimental data in the rapidity space. The predicted angular distribution is compared with experimental data in the energy range 50 to 200 GeV for proton reactions with Cu, Pb and emulsion nuclei as targets. The cluster parameters (mass, momentum, velocity and the particle multiplicity) are studied as a function of the number of target nucleons v encountered by the projectile.
