Abstract

We apply a large-scale summation of Feynman diagrams, including the class of parquet diagrams plus important contributions outside the parquet class, for calculating effective pairing interactions and subsequently the superfluid gap in P wave pairing in neutron matter. We use realistic nucleon-nucleon interactions of the v 8 type and perform calculations up to a Fermi momentum of 1.8 fm −1 . We find that many-body correlations lead to a strong reduction of the spin-orbit interaction, and, therefore, to a radical suppression of the 3 P 2 − 3 F 2 gap and an enhancement of the 3 P 0 gap.
