abstract
We present the first predictions for sub-threshold open charm and charmonium production in nuclear collisions. The production mechanism is driven by multi-step scatterings of nucleons and their resonance states, accumulating sufficient energy for the production of $J/\Psi$, $\Lambda_c + \overline{D}$ and $D+\overline{D}$. Our results are of particular importance for the CBM experiment at FAIR, as they indicate that already at the SIS100 accelerator one can expect a significant number of charmed hadrons to be produced. This opens new possibilities to explore charm dynamics and the formation of charmed nuclei.

Backward nucleon production by heavy baryonic resonances in proton-nucleus collisions
Backward nucleons in p+A collisions can be produced by heavy baryonic resonances that undergo successive rescatterings with nuclear nucleons, a mechanism the authors support with analytic kinematics and UrQMD simulations.
