Query: 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.
