In previous studies we have shown that hadrons, except for a pion, survive
the removal of the lowest lying Dirac eigenmodes from the valence quark
propagators. The low-modes are tied to the dynamical breaking of chiral
symmetry and we found chiral symmetry to be restored by means of matching
masses of chiral partners, like, e.g., the vector and axial vector currents.
Here we investigate the influence of removing the lowest part of the Dirac
spectrum on the locality of the Dirac operator. Moreover, we analyze the
influence of low-mode truncation on the quark momenta and thereupon on the
hadron spectrum and, finally, introduce a reweighting scheme to extend the
truncation to the sea quark sector.Comment: 7pages, 4 figures. Proceedings of the 31st International Symposium on
