Charmed baryon resonances with heavy-quark symmetry

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 ${\Lambda }_c(2595)$, ${\Lambda }_c(2660)$, ${\Sigma }_c(2902)$ or ${\Lambda }_c(2941)$, 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.
