Contribution

The paper presents a novel improved model that successfully captures key nuclear matter properties using non-linear meson fields under mean field approximation.

Findings

Successfully describes saturation properties of nuclear matter

Accurately predicts the equation of state and compressibility

Provides a comparative analysis with quark-meson coupling models

Abstract

An improved quark mass density- dependent model with the non-linear scalar sigma field and the $\omega$-meson field is presented. We show that the present model can describe saturation properties, the equation of state, the compressibility and the effective nuclear mass of nuclear matter under mean field approximation successfully. The comparison of the present model and the quark-meson coupling model is addressed.
