Query: Unbreaking chiral symmetry   In Quantum Chromodynamics (QCD) the eigenmodes of the Dirac operator with
small absolute eigenvalues have a close relationship to the dynamical breaking
of the chiral symmetry. In a simulation with two dynamical quarks, we study the
behavior of meson propagators when removing increasingly more of those modes in
the valence sector, thus partially removing effects of chiral symmetry
breaking. We find that some of the symmetry aspects are restored (e.g., the
masses of $\rho$ and $a_1$ approach each other) while confining properties
persist.
