# Scalar-isovector δ meson in the relativistic mean field theory and the structure of neutron stars with a quark core

@article{Alaverdyan2009ScalarisovectorM, title={Scalar-isovector $\delta$ meson in the relativistic mean field theory and the structure of neutron stars with a quark core}, author={Grigor Alaverdyan}, journal={Gravitation and Cosmology}, year={2009}, volume={15}, pages={5-9} }

In the framework of the relativistic mean field theory, we have considered the equation of state of superdense nuclear matter, taking into account an effective scalar-isovector δ meson field. The effect of the δ meson field on the characteristics of a Maxwell-type quark phase transition has been studied. The quark phase is described with the aid of the improved version of the MIT (Massachusetts Institute of Technology) bag model, in which interactions between the u, d, s quarks inside the bag…
