Constraints on nuclear matter parameters of an effective chiral model
Abstract
Within an effective nonlinear chiral model, we evaluate nuclear matter parameters exploiting the uncertainties in the nuclear saturation properties. The model is sternly constrained with minimal free parameters, which display the interlink among nuclear incompressibility (K), the nucleon effective mass (m⋆), the pion decay constant (fπ), and the σ-meson mass (mσ). The best fit among the various parameter set is then extracted and employed to study the resulting equation of state (EOS). Further, we also discuss the consequences of imposing constraints on the nuclear EOS from heavy-ion collision and other phenomenological model predictions.
