Screening Effects on $^1S_0$ Pairing in Neutron Matter
arXiv:nucl-th/0212027 · doi:10.1103/PhysRevC.67.061302
Abstract
The $^1S_0$ superfluidity of neutron matter is studied in the framework of the generalized Gorkov equation. The vertex corrections to the pairing interaction and the self-energy corrections are introduced and approximated on the same footing in the gap equation. A suppression of the pairing gap by more than 50% with respect to the BCS prediction is found, which deeply changes the scenario for the dynamical and thermal evolution of neutron stars.
