Abstract

We report meson spectra obtained by using valence overlap fermion propagators generated on a background of 2+1 flavor domain wall fermion gauge configurations on 16³ × 32, 24³ × 64 and 32³ × 64 lattices. We use many-to-all correlators with Z₃ grid source and low eigenmode substitution which is efficient in reducing errors for the hadron correlators. The preliminary results on meson spectrum, a₀ correlators, and charmonium hyperfine splitting for three sea quark masses are reported here.
