Resumo

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{*}(0) meson-exchange diagrams. We have also explored the production of the charm-baryon hypernucleus (16)(Lambda c+) O in the antiproton-O-16 collisions. For antiproton beam momenta of interest to the (P) over bar ANDA experiment, the 0 degrees differential cross sections for the formation of (16)(Lambda c+) O hypernuclear states with simple particle-hole configurations, have magnitudes in the range of a few mu b/sr.
