title

Exact Chiral Symmetry for Domain Wall Fermions with Finite $L_s$

collaboration

Robert G. Edwards

abstract

We show how the standard domain wall action can be simply modified to
allow arbitrarily exact chiral symmetry at finite fifth dimensional
extent $L_s$. We note that the method can be used for both quenched and
dynamical calculations. We test the method using smooth and
thermalized gauge field configurations. We also make comparisons of
the performance (cost) of the domain wall operator for spectroscopy
compared to other methods such as the overlap-Dirac operator and find
both methods are comparable in cost.
