Deconfinement Phase Transition in Neutron Stars and \delta-Meson Field
  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.
