Production of Λc+ hypernuclei in antiproton-nucleus collisions

We investigate the production of charm-baryon hypernucleus OΛc+16 in the antiproton-O16 collisions within a fully covariant model that is based on an effective Lagrangian approach. The explicit Λ¯c−Λc+ production vertex is described by the t-channel D0 and D⁎0 meson-exchanges in the initial collision of the incident antiproton with one of the protons of the target nucleus. The Λc+ bound state spinors as well as the self-energies of the exchanged mesons employed in our calculations are derived from the quark-meson coupling model. The parameters of various vertices are taken to be the same as those used in our previous study of the elementary p¯+p→Λ¯c−+Λc+ reaction. We find that for antiproton beam momenta of interest to the P¯ANDA experiment, the 0∘ differential cross sections for the formation of OΛc+16 hypernuclear states with simple particle-hole configurations, have magnitudes in the range of a few μb/sr.
