A Precursor of Chiral Symmetry Restoration in the Nuclear Medium
arXiv:nucl-th/9810022 · doi:10.1103/PhysRevLett.82.2840
Abstract
Spectral enhancement near the 2m_Ï threshold in the I=J=0 channel in nuclei is shown to be a distinct signal of the partial restoration of chiral symmetry. The relevance of this phenomenon with the possible detection of 2Ï^{0} and 2γin hadron-nucleus and photo-nucleus reactions is discussed.
