Title: What does a change in the quark condensate say about restoration of chiral symmetry in matter?

Abstract

The contribution of nucleons to the quark condensate in nuclear matter includes a piece of first order in {ital m}{sub {pi}}, arising from the contribution of low-momentum virtual pions to the {pi}{ital N} {sigma} commutator. Chiral symmetry requires that no term of this order appears in the {ital NN} interaction. The mass of a nucleon in matter thus cannot depend in any simple way on the quark condensate alone. More generally, pieces of the quark condensate that arise from low-momentum pions should not be associated with partial restoration of chiral symmetry. {copyright} {ital 1996 The American Physical Society.}
