| Abstract |
We present first results from a full QCD calculation on the CP-PACS, comparing various actions at a-1 1GeV and mπ/m0.7–0.9. We use the plaquette and a renormalization group improved action for the gluons, and the Wilson and the SW-Clover action for quarks. We find that significant improvements in the hadron spectrum results from improving the quarks, while the gluon improvement is required for a rotationally invariant static potential. An ongoing effort towards exploring the chiral limit in full QCD is described.
