POSSIBLE MOLECULAR STRUCTURES IN THE HEAVY BARYON SPECTRUM

Abstract

We use a chiral constituent quark model to study possible molecular structures in the heavy baryon spectrum. We first analyze D*N states and we find a bound state in the JP = 3/2- sector with an small binding energy. This state can be identified with the Λc(2940)+. The decays of this state are compatible with the existent experimental data. As a by product a state is predicted in the bottom baryon spectrum as a [Formula: see text] state with a mass around 6250 MeV. Moreover we also analyze other DN, D*N, DΔ and D*Δ states and their analogs in the bottom baryon sector finding several bound states.
