Abstract
The relativistic parametric coupling model is used here to describe global static properties of nuclear matter and neutron stars. Using recent observational data related to neutron star properties and experimental results of heavy-ion collisions, we review some properties of the effective model and we impose this way new constraints on its coupling constants. Then we analyze the consequences on already known parameters of nuclear matter, i.e., the compression modulus, the effective nucleon mass, and the maximum neutron star mass predicted by integrating the Tolman–Oppenheimer–Volkoff equations. To achieve this goal, we have explored the parametric coupling model in a wide range of parameters. We made use of recent data on flow analysis to constraint this parameter. Our results indicate values for the compression modulus of nuclear matter and for the maximum mass of neutron stars which are in good agreement with the observational data.
