Influence of σ * and φ Mesons on Λ Hyperon 1 S 0 Superfluidity in Neutron Star Matter

Within the framework of the relativistic mean field theory, we investigate the 1S0 superfluidity (SF) of ? hyperons in neutron star (NS) matter including ?* and mesons. The energy gap of ? hyperons is calculated with the Nijmegen one-boson-exchange potentials for a ?? pair. The parameter set we use is in line with the recent experimental data ?B??~1.01?0.20+0.18?0.11MeV. It is found that with ?* and mesons the pairing energy gap ?F of ? hyperons and the corresponding SF critical temperature TC?; are suppressed. In addition the NS mass range of ? hyperon SF is enlarged obviously.
