Description
We examine the properties of hyperons (Λ, Σ, Ξ) in dense baryon matter and neutron stars using a modified relativistic Dirac formalism (MRDF). In this approach, the quark meson (σ, ω) couplings are derived self-consistently at the quark level, where quark confinement is modelled through a scalar-vector linear potential, and corrections are incorporated for centre-of-mass motion, one-gluon exchange, and pionic contributions. We start by calculating the masses of baryons in a vacuum and then proceed to evaluate them within a medium. This work examines the properties of baryon matter, “such as the equation of state, compressibility, binding energy, and pressure. In addition, we compute essential parameters, including the baryon charge radius, axial-vector coupling constant, pion coupling constant, baryon sigma term, symmetry energy, density slope (L), and incompressibility (K₀)”.
