Abstract
The total yield of neutral D-mesons (4\(\pi \)) in central Xe + La interactions at 150 GeV per nucleon has been calculated within the Geant4 FTF model. Our results are consistent with predictions from other models based on Monte Carlo method that do not include quark-gluon plasma formation. Like those predictions, our calculation significantly underestimates the preliminary experimental data reported by the NA61/SHINE collaboration. The experimental data suggest enhanced production of charmed particles in nucleus-nucleus collisions. We also present calculations for charmed meson production in \(p + p\), \(d + d\), and \(^{{\text{4}}}{\text{He}} + \,{{\,}^{4}}{\text{He}}\) interactions for the future NICA/SPD experiment at \(\sqrt {{{s}_{{NN}}}} = \)10 and 20 GeV.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
