Quark-Gluon String Model and Its Application to Inelastic dC Interactions at a Momentum of 4.2 GeV/c per Nucleon

The fundamentals of the quark-gluon string (QGS) model for describing inelastic interactions of light nuclei at high energies are outlined. Basic ideas of the QGS model, which include the formation of quark-gluon strings, the choice of their limited number, and a simulation of breaking of a string with hadron formation, are presented. The results of theoretical calculations based on the QGS model are compared with experimental data obtained for inelastic dC interactions. A brief account of the procedure for obtaining these experimental data is given. An analysis and a comparison of model results and experimental information shows that the QGS model reproduces faithfully the interactions of colliding light nuclei at momenta around 4.2 GeV/c and is applicable up to nuclear-interaction energies corresponding to 10 GeV per nucleon.
