Production of charmed particles in proton-proton and light nucleus-nucleus interactions in Geant4 FTF model

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 calculation is close to predictions of Monte Carlo models that do not account for quark-gluon plasma formation. As the predictions, our calculation substantially underestimates preliminary experimental data. The experimental data indicate enhanced charmed particle production in nucleus-nucleus interactions. We present also our calculations for charmed meson production in $\mathrm{p}+\mathrm{p}$, $\mathrm{d}+\mathrm{d}$ and ${}^4\mathrm{He}{+}^4\mathrm{He}$ interactions for future NICA/SPD experiment at $\sqrt{s_{NN}}=$10 and 20 GeV.
