The D234 action for light quarks

Abstract
We investigate a new light fermion action (the ``D234'' action), which is accurate up to and tadpole-improved 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.
