Hot and dense hadronic matter in an effective mean-field approach

A Lavagno - Physical Review C—Nuclear Physics, 2010 - APS
We investigate the equation of state of hadronic matter at finite values of baryon density and
temperature reachable in high-energy heavy-ion collisions. The analysis is performed by …

Thermodynamical phases in a PNJL model at zero temperature

OA Mattos, T Frederico, O Lourenço - The European Physical Journal C, 2021 - Springer

mean-field models (in the hadronic phase) with the more updated versions of the Polyakov …

Critical behaviour of an effective relativistic mean field model in the presence of magnetic background and boundaries

LM Abreu, ES Nery - The European Physical Journal A, 2019 - Springer
In the present work we investigate the combined influence of magnetic background and
boundaries on the thermodynamic properties of effective relativistic mean field models, like …

Nuclear matter properties in the non-linear Walecka model at finite temperature with interaction between the σ-ω mesons

RS Costa, MR Cortes, DR Nunes… - AIP Conference …, 2014 - pubs.aip.org
In this work in contrast to the usual Walecka model [1] we include the interaction between
the σ–ω mesons [2, 3] with the aim of studying the nuclear matter properties in the relativistic …

Quark condensate and nucleon-antinucleon phase transition from hadronic models at finite temperature

O Lourenço, M Dutra, VS Timóteo, A Delfino - Nuclear Physics B …, 2010 - Elsevier
We investigate different hadronic model parametrizations at high temperature regime. All the
models were constructed to reproduce some observables at low temperature. At high …
