Improving meson two-point functions by low-mode averaging

High Energy Physics - Lattice 2009-11-10 v1

Abstract

Some meson correlation functions have a large contribution from the low lying eigenmodes of the Dirac operator. The contribution of these eigenmodes can be averaged over all positions of the source. This can improve the signal in these channels significantly. We test the method for meson two-point functions.
