摘要：

We investigate a new light fermion action (the ''D234'' action), which is accurate up to O(a(3)) and tadpole-improved O(a alpha(s)) errors. Using D234 with Symanzik- and tadpole-improved glue we find evidence that continuum results for the quenched hadron spectrum (pion, rho and nucleon) can be obtained on coarse lattices.
