Hadronic molecules in the open charm and open bottom baryon spectrum

Using a constituent quark model, we study possible molecular structures in the nonstrange open-charm and open-bottom spectrum. D(*)N, B¯(*)N, D(*)Δ, and B¯(*)Δ configurations are considered. We found molecular structures in all these channels. In particular, we describe the Λc(2940) as a D*N molecul...

Sumario:Using a constituent quark model, we study possible molecular structures in the nonstrange open-charm and open-bottom spectrum. D(*)N, B¯(*)N, D(*)Δ, and B¯(*)Δ configurations are considered. We found molecular structures in all these channels. In particular, we describe the Λc(2940) as a D*N molecule with JP=32−, whereas D(*)Δ structures may be an option for the recently discovered Xc(3250) and Xc(3212) resonances.
