We use a modified SU(2) chiral sigma model to study nuclear matter component and simple bag model for quark matter constituting a neutron star. We also study the phase transition of nuclear matter to quark matter with the mixed phase characterized by two conserved charges in the interior of highly dense neutron stars. Stable solutions of Tolman-Oppenheimer-Volkoff equations representing hybrid ...

The structure of the 5q configuration states with strangeness S = +1 is further studied in the chiral SU(3) quark model based on our previous work. We calculate the energies of fifteen low configurations of the 5q system, four lowest configurations of J π =

The Skyrme-Hartree-Fock-Bogoliubov code HFBTHO using the axial (2D) Transformed Harmonic Oscillator basis is tested against the HFODD (3D Cartesian HO basis) and HFBRAD (radial coordinate) codes. Results of large-scale ground-state calculations are presented for the SLy4 and SkP interactions.

The 3 P 0 decay model is briefly reviewed. Possible improvements, partly motivated by the examination of a microscopic description of a quark–anti-quark pair creation , are considered. They can provide support for the one-body character of the model which, otherwise, is difficult to justify. To some extent, they point to a boost effect that most descriptions of processes involving a pair creati...
