Is the U(1) symmetry restored at finite temperature or density?
Pedro Costa, M. C. Ruivo, C. A. de Sousa +1
We investigate the full U(3)U(3) chiral symmetry restoration, at finite temperature and density, on the basis of the three flavor Nambu-Jona-Lasinio model with the anomaly…
Phase transitions and behavior of kaons in hot and dense matter
C. A. de Sousa, Pedro Costa, M. C. Ruivo +1
We study phase transitions and the behavior of kaons in hot and dense matter, giving special attention to the role of strange quarks. At T=0, it is found that the fraction of the s…
Effective restoration of chiral and axial symmetries at finite temperature and density
M. C. Ruivo, Pedro Costa, C. A. de Sousa +1
The effective restoration of chiral and axial symmetries is investigated within the framework of the SU(3) Nambu-Jona-Lasinio model. The topological susceptibility, modeled from la…
Two photon decay of and at finite temperature and density
Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky
A comparative study of the anomalous decays , at finite temperature and at finite density, is performed in the framework of the three--flavor Nambu--Jona-Lasinio. The…
Anomalous decay of pion and eta at finite temperature
Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky
We study the anomalous decays in the framework of the three--flavor Nambu--Jona-Lasinio [NJL] model at finite temperature. The similarities and differences between th…
Charged pions and kaons weak leptonic decays at finite density
Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky
The weak leptonic decays and are investigated within the framew…
