Hadron spectroscopy and static quark potential in full QCD: A comparison of improved actions on the CP-PACS CP-PACS, Collaboration CP-PACS Collaboration Aoki, S Aoki S Boyd, G Boyd G Burkhalter, R Burkhalter R Hashimoto, S Hashimoto S Ishizuka, N Ishizuka N Iwasaki, Y Iwasaki Y Kanaya, K Kanaya K Kaneko, T Kaneko T Kuramashi, Y Kuramashi Y Okawa, Masanori Okawa Masanori Ukawa, A Ukawa A Yoshié, T Yoshié T open access Copyright (c) 1998 Elsevier Science B.V. 420 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.
