Relativistic Mean-Field Hadronic Models under Nuclear Matter Constraints

Relativistic mean-field (RMF) models have been widely used in the study of many hadronic frameworks because of several important aspects not always present in nonrelativistic models, such as intrinsic Lorentz covariance, automatic inclusion of spin, appropriate saturation mechanism for nuclear matter, causality and, therefore, no problems related to superluminal speed of sound. With the aim of identifying the models which best satisfy well known properties of nuclear matter, we have analyzed

Inverse magnetic catalysis in the ( 2 + 1 ) -flavor Nambu–Jona-Lasinio and Polyakov–Nambu–Jona-Lasinio models

Vector interaction strength in Polyakov-Nambu-Jona-Lasinio models from hadron-quark phase diagrams

parameterizations of seven different types of RMF models under three different sets of constraints related to symmetric nuclear matter, pure neutron matter, symmetry energy, and its derivatives. One of these (SET1) is formed of the same constraints used in a recent work [M. Dutra et al., Phys. Rev. C 85, 035201 (2012)] in which we analyzed

Polyakov–Nambu–Jona-Lasinio phase diagrams and quarkyonic phase from order parameters

Hadron-quark phase transition in a hadronic and Polyakov–Nambu–Jona-Lasinio models perspective

Skyrme parameterizations. The results pointed to

Correlations between the nuclear matter symmetry energy, its slope, and curvature from a nonrelativistic solvable approach and beyond

2

Correlations between critical parameters and bulk properties of nuclear matter

models consistent with all constraints. By using another set of constraints, namely, SET2a, formed by the updated versions of the previous one, we found

Correlations between bulk parameters in relativistic and nonrelativistic hadronic mean-field models

4

Correlations between the nuclear matter symmetry energy, its slope, and curvature

models approved simultaneously. Finally, in the third set, named SET2b, in which the values of the constraints are more restrictive, we found
