Abstract: Relativistic models can be successfully applied to the description of compactstar properties in nuclear astrophysics as well as to nuclear matter and finitenuclei properties, these studies taking place at low and moderate temperatures.Nevertheless, all results are model dependent and so far it is unclear whethersome of them should be discarded. Moreover, in the regime of hot hadronicmatter very few calculations exist using these relativistic models, inparticular when applied to particle yields in heavy ion collisions.In the present work we comment on the known constraints that can help theselection of adequate models in this regime and investigate the maindifferences that arise when the particle production during a Au+Au collision atRHIC is calculated with different models.
