Charm baryon-kaon molecules

This paper predicts several possible molecular pentaquarks composed of a charm baryon (Lambda_c or Sigma_c) bound to a kaon or kaon star meson. Using a one-boson exchange model and considering coupled channels, the analysis finds candidates for loosely bound states with quantum numbers matching recent LHCb observations.
