Web-page on UrQMD Model Validation

A WEB-page containing materials of comparing experimental data and UrQMD model calculations has been designed. The page provides its user with a variety of tasks solved with the help of the model, accuracy and/or quality of experimental data description, and so on. The page can be useful for new experimental data analysis, or new experimental research planning. The UrQMD model is cited in more than 272 publications. Only 44 of them present original calculations. Their main results on the model are presented on the page.

Patches to UrQMD Model Code

Patches to the code of the Ultra-relativisic Quantum Molecular Dynamics model (UrQMD version 1.3) are described. They improve the code operation. The most important one is done for the file ANNDEC.F.

Analysis of pC-interactions at Momentum of 4.2 GeV/c Within Framework of FRITIOF and Cascade Models

Experimental data on multiplicities and kinematical characteristics of $π^-$, $π^+$ mesons and protons in the interactions of protons with carbon nucleus at momentum 4.2 GeV/c in a dependence of collision centrality are analyzed. Parameter Q which is a difference between multiplicities of positive and negative charged particles without multiplicity of slow protons with momentum less than 0.3 GeV/c in an event, is taken as a criteria of collision centrality. The experimental data on events with different centrality are compared with predictions of the cascade-evaporation model and the modified FRITIOF model. For the first time, non-nucleonic degrees of freedom in nuclei ($Δ^+, Δ^0 $ isobars) are taken into account in the FRITIOF model, and a commonly good description of the secondary particles characteristics is reached.
