We present and discuss results for cutoff effects in the PCAC masses and the mass dependence of r0 for full QCD and various fermion actions. Our discussion of how one computes mass dependences – here of r0 – is also relevant for comparisons with chiral perturbation theory.

We present results of phase shift for I = 2 S-wave ππ system with the Wilson fermions in the quenched approximation. The finite size method proposed by Lüscher is employed, and calculations are carried out at

We report on our calculation of K → π vector form factor by numerical simulations of two-flavor QCD on a 16 3 × 32 × 12 lattice at a 0.12 fm using domain-wall quarks and DBW2 glue. Our preliminary result at a single sea quark mass correponding to m PS /m V 0.53 shows a good agreement with previous estimate in quenched QCD and that from a phenomenological… (More)

We report the final results of the CP-PACS calculation for the quenched light hadron spectrum with the Wilson quark action. Our data support the presence of quenched chiral singularities, and this motivates us to use mass formulae based on quenched chiral perturbation theory in order to extrapolate hadron masses to the physical point. Hadron masses and… (More)

We describe the main building blocks of a generic automated package for the calculation of Feynman diagrams. These blocks include the generation and creation of a model file, the graph generation, the symbolic calculation at an intermediate level of the Dirac and tensor algebra, implementation of the loop integrals, the generation of the matrix elements or… (More)

We present a report on a calculation of scattering length for I = 2 S-wave two-pion system from two-pion wave function. Calculations are made with an RG-improved action for gluons and improved Wilson action for quarks at a −1 = 1.207(12) GeV on 16 3 × 80, 20 3 × 80 and 24 3 × 80 lattices. We investigate the validity of necessary condition for application of… (More)

We report on a calculation of BK with domain wall fermion action in quenched QCD. Simulations are made with a renormalization group improved gauge action at β = 2.6 and 2.9 corresponding to a −1 ≈ 2GeV and 3GeV. Effects due to finite fifth dimensional size N5 and finite spatial size Nσ are examined in detail. Matching to the continuum operator is made… (More)
