Abstract

We study a generalized ladder diagram resummation in the superfluid phase of nuclear matter. The approach is based on a conserving generalization of the usual T-matrix approximation including also anomalous self-energies and propagators. The approximation here discussed is a generalization of the usual mean-field BCS approach to superfluidity. The numerical results in this work are obtained in the quasiparticle approximation. Properties of the resulting self-energy, superfluid gap, and spectral functions are studied.
