Chiral approach to nuclear matter: Role of two-pion exchange with virtual delta-isobar excitation
S. Fritsch, N. Kaiser, W. Weise
We extend a recent three-loop calculation of nuclear matter in chiral perturbation theory by including the effects from two-pion exchange with single and double virtual -i…

Chiral approach to nuclear matter: Role of explicit short-range NN-terms
S. Fritsch, N. Kaiser
We extend a recent chiral approach to nuclear matter by including the most general (momentum-independent) NN-contact interaction. Iterating this two-parameter contact-vertex with i…
