Charmed baryon resonances with heavy-quark symmetry

arXiv:0906.3759 · doi:10.1088/1674-1137/33/12/046

Abstract

We study charmed baryon resonances that are generated dynamically from a coupled-channel unitary approach that implements heavy-quark symmetry. Some states can already be identified with experimental observations, such as $Λ_c(2595)$, $Λ_c(2660)$, $Σ_c(2902)$ or $Λ_c(2941)$, while others need a compilation of more experimental data as well as an extension of the model to include higher order contributions. We also compare our model to previous SU(4) schemes.
