TL;DR: In this paper, an optimized search for oscillations using free neutrons from a slow neutron moderator could improve existing limits on the free oscillation probability by at least three orders of magnitude.

Precursor of Chiral Symmetry Restoration in the Nuclear Medium
TL;DR: Spectral enhancement near the 2m √ √ σ σ 0 threshold in the nuclei is a distinct signal of the partial restoration of chiral symmetry as mentioned in this paper, and the relevance of this phenomenon with the possible detection of $2
