Unquenched Studies Using the Truncated Determinant Algorithm

摘要

A truncated determinant algorithm is used to study the physical effects of thequark eigenmodes associated with eigenvalues below 420 MeV. This initial high statistics study focuses on coarse 6(sup 4) lattices with O(a(sup 2)) improved gauge action, light internal quark masses and large physical volumes. Three features of full QCD are examined: topological charge distributions, string breaking as observed in the static energy and the eta prime mass.
