Finite ma Errors in Overlap Fermions
Presenter: Shao-Jing Dong — University of Kentucky

Finite ma errors with overlap fermions are studied by calculating the dispersion relation and hyperfine splitting between vector and pseudoscalar mesons on various isotropic and anisotropic quenched lattices. We find that the ma errors are mostly propotional to (ma)2 and suggest that ma should be limited to less than 0.5 in order to keep the systematic ma errors below 3 to 5% level.
