Quark model description of the Λ_c(2940)^+ as a molecular D^*N state and the possible existence of the Λ_b(6248)

P. G. Ortega, D. R. Entem, F. Fernández

The Λ_c(2940)^+ baryon is studied in a constituent quark model as a molecular state composed by nucleons and D^* mesons. A bound state with the right binding energy is found for th…

Molecular structures in charmonium spectrum: The $X Y Z$ puzzle

P. G. Ortega, D. R. Entem, F. Fernandez

We study in the framework of a constituent quark model the possible contributions of molecular structures to the XYZ charmonium like states. We analyze simultaneously the $c\bar{c}…
