Ground state properties of charmed hypernuclei within a mean field approach

Closed shell charmed hypernuclei Li Λ c5, F Λ c17, Sc Λ c41, Cu Λ c57, Sb Λ c133, and Bi Λ c209 are calculated within the Hartree-Fock approach by using three different force sets derived from microscopic Brueckner-Hartree-Fock calculations of Λ hypernuclei. Ground state properties (binding energies, Λ c separation energies, Λ c single particle energies, and Λ c densities) of charmed nuclei are examined. We confirm the results and conclusions of different models from the literature, related to Λ c hypernuclei. Due to the Coulomb repulsion between protons and the Λ c baryon, charmed hypernuclei are most bound for 16≤A≤41, where F Λ c17 can be considered as an excellent candidate to determine charmed hypernuclei properties. The competition between the attractive nucleon- Λ c interaction and the Coulomb repulsion is discussed, and we compare Λ and Λ c hypernuclei properties.
