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…
Strong and Electromagnetic Mass Splittings in Heavy Mesons
Jose L. Goity, Chandana P. Jayalath
The contributions to heavy meson mass differences by the strong hyperfine interaction, the light quark masses and the electromagnetic interaction are obtained from the empirical va…
Photo-production of Positive Parity Excited Baryons in the 1/Nc Expansion of QCD
Jose L. Goity Norberto N. Scoccola
We analyze the photo-production helicity amplitudes for the positive parity excited baryons in the context of the expansion of QCD. The results show that sub-leading correc…
