Topic: Chiral Fermions

Ginsparg-Wilson Games

Abstract: Fat link fermion actions have pretty good chiral properties but don't have any direct connection to an action obeying the Ginsparg-Wilson condition. I show how one can sneak up on a fairly good implementation of the G-W relation (in quenched 4-D SU(3)) with low order expansions of appropriately chosen actions, costing 10-20 times the clover action. This isn't very deep or original but the results might be interesting.
