$$^{1}S_{0}$$ proton superfluidity in neutron star matter; Impact of bulk properties

Tanigawa, Tomonori; Matsuzaki, Masayuki*; Chiba, Satoshi

We study the $$^{1}S_{0}$$ proton pairing gap in neutron star matterputting emphasis on influence of the Dirac effective mass and theproton fraction on the gap within the relativistic Hartree-Bogoliubovmodel. The gap equation is solved using the Bonn-B potential as aparticle-particle channel interaction. It is found that the maximalpairing gap $$Delta_mathrm{max}$$ is 1-2MeV, which has a strongcorrelation with the Dirac effective mass. Hence we suggest that itserves as a guide to narrow down parameter sets of the relativisticeffective field theory. Furthermore, the more slowly protons increasewith density, the lower the peak of the gap and the wider thesuperfluid range become.

Possibility of $$LambdaLambda$$ pairing and its dependence on background density in a relativistic Hartree-Bogoliubov model

Tanigawa, Tomonori; Matsuzaki, Masayuki*; Chiba, Satoshi

Physical Review C, 68(1), p.015801_1 - 015801_8, 2003/07

We calculate a $$LambdaLambda$$ pairing gap in binary mixed matter of nucleons and $$Lambda$$ hyperons within the relativistic Hartree-Bogoliubov model since a recent experiment suggests a weaker $$LambdaLambda$$ attraction than before, which has a significant impact on properties of neutron stars in various aspects. Lambda hyperons to be paired up are immersed in background nucleons in normal state. A phenomenological $$LambdaLambda$$ interaction, which is derived relativistically from the Lagrangian of the system, is adopted to the gap equation. It is found that at background density $$rho_{N}=2.5rho_{0}$$ the $$LambdaLambda$$ pairing gap is very small, and that denser background makes it rapidly suppressed. This result suggests a mechanism, specific to mixed matter dealt with relativistic models, of its dependence on the nucleon density.
