Anomalous decay of pion and eta at finite density

Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky

We study the anomalous decays $π^{0}, η \to γ γ$ in the framework of the three--flavor Nambu--Jona-Lasinio [NJL] model, in the vacuum and in quark matter in $β$ --equilibrium. It is fou…

$η - η^{'}$ in a hot and dense medium

Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky

The behavior of $η$ and $η^{'}$ in hot strange quark matter in weak equilibrium with temperature, is investigated within the SU(3) Nambu-Jona-Lasinio [NJL] model. Possible manifestati…

Pseudoscalars Mesons in Hot, Dense Matter

Pedro Costa, M. C. Ruivo, Yu. L. Kalinovsky +1

Phase transitions in hot and dense matter and the in--medium behavior of pseudoscalar mesons ( $π^{\pm}, π^{0}, K^{\pm}, K^{0}, K ˉ^{0}, η an d η^{'}$ ) are investigated, in the framework…
