Color neutrality effects in the phase diagram of the PNJL model
D. Gomez Dumm, D. B. Blaschke, A. G. Grunfeld +1
The phase diagram of a two-flavor Polyakov loop Nambu-Jona-Lasinio model is analyzed imposing the constraint of color charge neutrality. Main effects of this constraint are a shrin…
Nonlocal chiral quark models with wavefunction renormalization: sigma properties and π-πscattering parameters
S. Noguera, N. N. Scoccola
We analyze the sigma meson mass and width together with the pion-pion scattering parameters in the context of non-local chiral quark models with wave-function renormalization (WFR)…
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…
Nonlocal SU(3) chiral quark models at finite temperature: the role of the Polyakov loop
Gustavo A. Contrera, Daniel Gomez Dumm, Norberto N. Scoccola
We analyze the role played by the Polyakov loop in the description of the chiral phase transition within the framework of nonlocal SU(3) chiral models with flavor mixing. We show t…
Skyrmions in the presence of isospin chemical potential
J. A. Ponciano, N. N. Scoccola
We analyze the existence of localized finite energy topological excitations on top of the perturbative pion vacuum within the Skyrme model at finite isospin chemical potential and…
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…
