Finite ma corrections for sea quark matrix elements

High Energy Physics - Lattice 2009-10-28 v2

Abstract

We discuss the finite mama corrections associated with the computation of sea quark matrix elements. We find them to differ from the standard normalization used for valence quarks and to depend strongly on the Lorentz structure of the current under consideration. Phenomenological implications of these results are briefly discussed in two examples. We also mention how the magnitude of the correction factors can be reduced by using a 2-link improved action.
