| dc.description | The contribution of nucleons to the quark condensate in nuclear matter includes a piece of first order in $m_π$, arising from the contribution of low-momentum virtual pions to the $πN$ sigma commutator. Chiral symmetry requires that no term of this order appears in the $NN$ 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. | |
