Finite ma Errors of the Overlap Fermion

Dong, S. J., Liu, K. F.

Understand

In this talk, we shall assess the finite ma errors from the overlap fermion.

  • We shall present results on the speed of light from the dispersion relation and hyperfine splitting between the vector and pseudoscalar mesons as a function to ma to reveal the m\Lambda_{QCD}a^2 and m^2a^2 errors.
  • We conclude from this study that one should be limited to using ma less than 0.5 in order to keep the systematic ma errors below a few percent level.
