TL;DR
This paper investigates how the inclusion of the elta-meson field affects the deconfinement phase transition in neutron stars, using relativistic mean-field theory and the MIT bag model.
Contribution
It introduces the elta-meson field into the RMF model for neutron star matter and analyzes its impact on the deconfinement transition boundary.
Findings
The elta-meson field influences the transition boundary characteristics.
The study compares Maxwell and Glendenning construction scenarios.
The effects of perturbative one-gluon exchange are considered in the quark phase.
Abstract
The Maxwell and Glendenning construction scenarios of deconfinement phase transition in neutron star matter are investigated. The hadronic phase is described within the relativistic mean-field (RMF) theory, if also the scalar-isovector \delta-meson field is taken into account. The strange quark phase is described in the frame of MIT bag model, including the effect of perturbative one-gluon exchange interactions. The influence of the \delta-meson field on the deconfinement phase transition boundary characteristics is discussed.
