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 ${\rm p+p}$, ${\rm d+d}$ and ${\rm ^4He+^4He}$ interactions for future NICA/SPD experiment at $\sqrt{s_{NN}}=$10 and 20 GeV.
