Light and heavy baryon masses: the 1/N_c expansion and the quark model
F. Buisseret, C. Semay, Fl. Stancu +1
We establish a connection between the quark model and the 1/N_c expansion mass formulas used in the description of baryon resonances. We show that a remarkable compatibility exists…
Group Theoretical Analysis of the Wave Function of the Nonstrange Baryons in the Expansion
N. Matagne, Fl. Stancu
Using standard group theoretical techniques we construct the exact wave function of the multiplet in the orbital, spin and flavor space. This symmetric wave functi…
The wave function of baryons in the expansion
N. Matagne, Fl. Stancu
Much work has been devoted to the study of nonstrange baryons belonging to the multiplet in the framework of the expansion. Using group theoretical argu…
Analysis of Negative Parity Baryon Photoproduction Amplitudes in the Expansion
N. N. Scoccola, J. L. Goity, N. Matagne
We study the photoproduction helicity amplitudes of negative parity baryons in the context of the expansion of QCD. A complete analysis to next-to-leading order is carried…
Baryon Regge Trajectories in the Light of the Expansion
J. L. Goity, N. Matagne
We analyze Regge trajectories in terms of the expansion of QCD. Neglecting spin-orbit contributions to the large baryon mass operator, we consider the evolution of th…
Baryonic mass formula in large QCD versus quark model
C. Semay, F. Buisseret, N. Matagne +1
We establish a connection between the quark model results and the expansion mass formula used in the description of baryon resonances. We show that a remarkable compatibili…
