One-body Properties of Nuclear Matter with Off-shell Propagation

Abstract

Symmetric nuclear matter is studied in the self-consistent, in-medium $T$-matrix approach. One-body spectral function, optical potential, and scattering width are calculated. Properties of quasi-particle excitations at the Fermi surface are discussed. Dispersive self-energies are dominated by contributions from the ${}^1{S}_0$, $3S_1{-}^3{D}_1$, and ${}^3{P}_1$ partial waves.
