Unlike for unsmeared Wilson fermions, the resulting clover coefficients are close to the tree-level value even at coarse lattice spacings, indicating the absence of large cutoff effects. A number of exploratory tests are also performed with the improved action.7 pages, 6 figures, contribution to Lattice 2007, Regensburg, GermanyHigh Energy Physics - Latticetext
