Abstract
The [Formula: see text] nucleon superfluidity in neutron star matter was investigated in the framework of relativistic [Formula: see text] model with the tensor couplings of [Formula: see text] and [Formula: see text] mesons using the relativistic Hartree–Fock (RHF) approximation. It was found that the tensor couplings of [Formula: see text] and [Formula: see text] mesons lead to a clear growth of the [Formula: see text] neutron pairing gap in the density range where there exists [Formula: see text] neutron superfluidity. The [Formula: see text] pairing gap of proton with the tensor couplings of [Formula: see text] and [Formula: see text] mesons in the density range of [Formula: see text]–[Formula: see text][Formula: see text]fm[Formula: see text] is lower and then in the density range of [Formula: see text]–[Formula: see text][Formula: see text]fm[Formula: see text] higher than the corresponding value without the tensor couplings of [Formula: see text] and [Formula: see text] mesons. Our results provide a basic to understand the influence of the tensor couplings of [Formula: see text] and [Formula: see text] mesons on the cooling properties of neutron star.
