Compact star and compact star matter properties from a baryonic extended linear sigma model with explicit chiral symmetry breaking
Yao Ma, Yong-Liang Ma, Lu-Qi Zhang
Based on a baryonic extended linear sigma model including explicit chiral symmetry breaking effect, the structure of neutron stars with the emergence of hyperons is investigated us…

Composition of scalar mesons and their effects on nuclear matter properties in an extended linear sigma model
Yao Ma, Yong-Liang Ma
It has been argued that the iso-scalar and iso-vector mesons play significant roles in nuclear matter and neutron star structures. We improve the extended linear sigma model with b…
