Constraints on the coupling constants of σ − and ω − mesons to ∆-isobars
The effects of the presence of ∆-isobars in nuclear matter are studied in the framework of relativistic mean-field theory. The existence of stable nuclei at saturation density imposes constraints on the coupling constants of the σand ω-meson with ∆-isobars. The range of possible values for the scalar and vector coupling constants of ∆-isobars with respect to the nucleon coupling is investigated and compared to recent predictions of QCD sum rule calculations.
The Relativistic Nuclear Many Body Problem
These lectures are based on a book “THE RELATIVISTIC NUCLEAR MANY-BODY PROBLEM” written with Brian Serot which will appear as volume 16 of the series Advances in Nuclear Physics edited by J. W. Negele and E. Vogt [R1]. I am distributing copies of the table of contents.
Can a neutron star be a giant MIT bag
Abstract We show, on the basis of the M.I.T. bag model of hadrons, that a neutron matter-quark phase transition is energetically favorable at densities around ten to twenty times nuclear matter density. It is unlikely, however, that quark matter can be found within stable neutron stars, or that it may form a third family of dense stellar objects.
