Full QCD simulation on CP - PACS ∗
نویسندگان
چکیده
A status report is made of an on-going full QCD study on the CP-PACS aiming at a comparative analysis of the effects of improving gauge and quark actions on hadronic quantities and static quark potential. Simulations are made for four action combinations, the plaquette or an RG-improved action for gluons and the Wilson or SWclover action for quarks, at a ≈ 1.1-1.3GeV and mπ/mρ ≈ 0.7-0.9. Results demonstrate clearly that the clover term markedly reduces discretization errors for hadron spectrum, while adding six-link terms to the plaquette action leads to much better rotational symmetry in the potential. These results extend experience with quenched simulations to full QCD.

3 × 48 lattices. Four sea quark masses having mPS/mV ≈ 0.8–0.6 are simulated, for each of which hadron masses are evaluated for valence quark masses corresponding to mPS/mV ≈ 0.8–0.5. Results for hadron and light quark masses are presented and compared with those obtained in quenched QCD.
متن کاملRecent Results from the CP - PACS Collaboration
We present an overview of recent results from the CP-PACS computer on the quenched light hadron spectrum and an ongoing two-flavour full QCD study. We find that our quenched hadron mass results are compatible with the mass formulae predicted by quenched chiral perturbation theory, which we adopt in our final analysis. Quenched hadron masses in the continuum limit show unambiguous and systematic...

The aim of the CP-PACS project was to develop a massively parallel computer for performing numerical research in computational physics with primary emphasis on lattice QCD. The CP-PACS computer with a peak speed of 614 GFLOPS with 2048 processors was completed in September 1996, and has been in full operation since October 1996. We present an overview of the CP-PACS project and describe charact...
متن کاملHadron spectroscopy and static quark potential in full QCD : A comparison of improved actions on the CP - PACS ∗
We present first results from a full QCD calculation on the CP-PACS, comparing various actions at a ∼ 1GeV and mπ/mρ ≈ 0.7–0.9. 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 ...
