Optimizing the Chiral Properties of Lattice Fermion Actions

Abstract

We describe a way to optimize the chiral behavior of Wilson-type lattice fermion actions by studying the low energy real eigenmodes of the Dirac operator. We find a candidate action, the clover action with fat links with a tuned clover term. We present a calculation of spectroscopy and matrix elements at Wilson gauge coupling $\beta =5.7$. The action shows good scaling behavior.
