Dibaryons in Nuclear Matter
The possibility for occurrence of a Bose condensate of dibaryons in nuclear matter is investigated within the framework of the Walecka model in the mean-field approximation. Constraints for the ωand σ-meson coupling constants with dibaryons following from the requirement of stability of dibaryon matter against compression are derived and the effect of σand π-meson exchange current contributions...
متن کاملDibaryons from Exceptional Collections
We discuss aspects of the dictionary between brane configurations in del Pezzo geometries and dibaryons in the dual superconformal quiver gauge theories. The basis of fractional branes defining the quiver theory at the singularity has a K-theoretic dual exceptional collection of bundles which can be used to read off the spectrum of dibaryons in the weakly curved dual geometry. Our prescription ...
متن کاملPossible Dibaryons with Strangness S=-5
In the framework of RGM, the binding energy of the six quark system with strangeness s=-5 is systematically investigated under the SU(3) chiral constituent quark model. The single Ξ * Ω channel calculation with spins S=0 and 3 and the coupled ΞΩ and Ξ * Ω channel calculation with spins S=1 and 2 are considered, respectively. The results show following observations: In the spin=0 case, Ξ * Ω is ...
متن کاملσ-Mesons with Dibaryons
The effect of narrow dibaryon resonances to nuclear matter and structure of neutron stars is investigated in the mean-field theory (MFT) and in the relativistic Hartree approximation (RHA). The existence of massive neutron stars imposes constraints to the coupling constants of the ωand σ-mesons with dibaryons. We conclude that the experimental candidates to dibaryons d1(1920) and d’(2060) if ex...
متن کاملThe interaction between H-dibaryons
We investigate the interaction between H-dibaryons employing a quark cluster model with a one-gluon-exchange potential and an effective meson exchange potential (EMEP). A deeply-bound state of two H-dibaryons due to the medium range attraction of the EMEP is obtained. The bound H–H system has a size of about 0.8 ∼ 0.9 fm because of the short-range repulsion generated by the color-magnetic inter...
