Three-body force effect on off-shell mass operator and spectral functions in nuclear matter

Pei Wang, Sheng-Xin Gan, Peng Yin +1

Within the framework of the Brueckner theory, the off-shell behaviors of the mass operator $M(k,\omega )=V(k,\omega )+iW(k,\omega )$, i.e., its dependence upon the momentum $k$ and upon the nucleon…
