Charm production in interactions of antiproton with proton and nuclei at $\bar{P}ANDA$ energies

Abstract

We study the production of charmed baryons in the antiproton-proton and antiproton-nucleus interactions within a fully covariant model that is based on an effective Lagrangian approach. The baryon production proceeds via the $t$-channel $D^0$ and $D^{\ast 0}$ meson-exchange diagrams. We have also explored the production of the charm-baryon hypernucleus ${}_{{\Lambda }_c^{+}}^{16}$O in the antiproton - ${}^{16}$O collisions. For antiproton beam momenta of interest to the $\bar{P}ANDA$ experiment, the 0${}^{\circ }$ differential cross sections for the formation of ${}_{{\Lambda }_c^{+}}^{16}$O hypernuclear states with simple particle-hole configurations, have magnitudes in the range of a few $\mu$b/sr.
