Deconfinement of neutron star matter within the Nambu-Jona-Lasinio model
G. Lugones, A. G. Grunfeld, N. N. Scoccola +1
We study the deconfinement transition of hadronic matter into quark matter under neutron star conditions assuming color and flavor conservation during the transition. We use a two-…
Mass and chemical asymmetry in QCD matter
L. F. Palhares, E. S. Fraga, C. Villavicencio
We consider two-flavor asymmetric QCD combined with a low-energy effective model inspired by chiral perturbation theory and lattice data to investigate the effects of masses, isosp…
QCD Effective action at high temperature and small chemical potential
C. Villavicencio, E. S. Fraga
We present a construction of an effective Yang-Mills action for QCD, from the expansion of the fermionic determinant in terms of powers of the chemical potential at high temperatur…
Diagrammatics of the Dimensionally Reduced Action in phi^4 theory
C. Villavicencio, C. A. A. de Carvalho
We describe the Feynman rules for the construction of the Dimensionally Reduced Action (DRA) for a phi^4 field theory, as well as rules for the construction of the connected Green…
Two-flavor condensates in chiral dynamics: temperature and isospin density effects
M. Loewe, C. Villavicencio
Isospin density and thermal corrections for several condensates are discussed, at the one-loop level, in the frame of chiral dynamics with pionic degrees of freedom. The evolution…
Thermal pion masses in the second phase:
M. Loewe, C. Villavicencio
Density and thermal corrections to the mass of the pions are studied in the framework of the SU(2) low energy effective chiral lagrangian, in terms of the isospin chemical potentia…
