Perturbative Subtraction Methods

The effects of an automated, tenth order in $κ$ subtraction scheme on the noise variance of various Wilson QCD disconnected matrix elements are examined. It is found that there is a dramatic reduction in the variance of the lattice point-split electromagnetic currents and that this reduction persists at small quark mass.
