摘要：Using Schrödinger functional techniques, we determine the coefficient of the clover term necessary
for non-perturbative O(a) improvement of hypercubic smeared Wilson fermions on a
quenched plaquette action background. 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.
