Is there a pion-Lambda-nucleon bound state?
Avraham Gal, Humberto Garcilazo
We have searched for bound states in the pion-Lambda-nucleon system by solving the nonrelativistic Faddeev equations, as well as a relativistic version, with input separable pion-n…
Quark-model hadron structure
A. Valcarce, J. Vijande, P. Gonzalez +1
We review some selected recent results on hadron spectroscopy and related theoretical studies based on constituent quark models.
Symmetry patterns in the spectrum
P. Gonzalez, J. Vijande, A. Valcarce +1
We revise the role played by symmetry in the study of the low-lying baryon spectrum and comment on the difficulties when trying to generalize the symmetry pattern to higher energy…
A scheme for nonstrange baryons
P. Gonzalez, J. Vijande, A. Valcarce +1
We show that nonstrange baryon resonances can be classified according to multiplets of . We identify spectral regularities and degeneracies that allow us to pred…
