On Skyrmion semiclassical quantization in the presence of an isospin chemical potential
Thomas D. Cohen, Juan A. Ponciano, Norberto N. Scoccola
The semiclassical description of Skyrmions at small isospin chemical potential is carefully analyzed. We show that when the calculation of the energy of a nucleon is performe…
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…
Equation of state for hybrid compact stars with a nonlocal chiral quark model
A. G. Grunfeld, J. Berdermann, D. B. Blaschke +3
We study the thermodynamics of two flavor color superconducting (2SC) quark matter within a nonlocal chiral quark model, using both instantaneous and covariant nonlocal interaction…
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…
