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…
Hyperspherical harmonic study of identical-flavor four-quark systems
J. Vijande, N. Barnea, A. Valcarce
We present an exact method based on a hyperspherical harmonic expansion to study systems made of quarks and antiquarks of the same flavor. Our formalism reproduces and improves the…
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…
Understanding open-charm mesons
J. Vijande, F. Fernandez, A. Valcarce
We present a theoretical framework that accounts for the new and mesons measured in the open-charm sector. These resonances are properly described if considered as a…
Hyperspherical harmonic formalism for tetraquarks
J. Vijande, N. Barnea, A. Valcarce
We present a generalization of the hyperspherical harmonic formalism to study systems made of quarks and antiquarks of the same flavor. This generalization is based on the symmetri…
Dynamical study of mesons
J. Vijande, A. Valcarce, K. Tsushima
It has been recently conjectured by Selem and Wilczek \cite{Sel06} the existence of a meson due to strong correlations between the two light antiquarks. We mak…
