| 英文摘要 | Within the framework of the relativistic mean field theory, we investigate the S-1(0) superfluidity (SF) of Lambda hyperons in neutron star (NS) matter including sigma* and phi mesons. The energy gap of Lambda 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 Delta B-Lambda Lambda similar to 1.01 +/- 0.20(-0.11)(+ 0.18) MeV. It is found that with sigma* and phi mesons the pairing energy gap Delta(F) of Lambda hyperons and the corresponding SF critical temperature T-C Lambda are suppressed. In addition the NS mass range of Lambda hyperon SF is enlarged obviously. |
