Dilute Nuclear Matter in Chiral Perturbation Theory
arXiv:nucl-th/0303019 · doi:10.1103/PhysRevC.69.035211
Abstract
We use chiral perturbation theory to compute the effective nucleon propagator in an expansion about low density in the chiral limit. We neglect four-nucleon interactions and focus on pion exchange. Evaluating the nucleon self-energy on its mass shell to leading order, we show that the effective nucleon mass increases by a small amount. We discuss the relevance of our results to the structure of compact stars.
Manuscript rewritten, especially conclusions about mass shifts; contact terms cannot be neglected. Computation unchanged
