چکیده
We present results of a large-scale simulation for the flavor non-singlet light hadron spectrum in quenched lattice QCD with the Wilson quark action. Hadron masses are calculated at four values of lattice spacing in the range a ≈ 0.1 – 0.05 fm on lattices with a physical extent of 3 fm at five quark masses corresponding to mπ/mρ ≈ 0.75 – 0.4. The calculated spectrum in the continuum limit shows a systematic deviation from experiment, though the magnitude of deviation is contained within 11%. Results for decay constants and light quark masses are also reported. 11.15.Ha, 11.30.Rd, 12.15.Ff, 12.38.Gc, 14.20.-c, 14.40.-n Typeset using REVTEX

A status report is made of an ongoing 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 SW-clover action for quarks, at a −1 ≈ 1.1-1.3GeV and mπ/mρ ≈ 0.7-0.9. Res...

We investigate a new light fermion action (the " D234 " action), which is accurate up to O(a 3) and tadpole-improved O(aαs) errors. Using D234 with Symanzik-and tadpole-improved glue we find evidence that continuum results for the quenched hadron spectrum (pion, rho and nucleon) can be obtained on coarse lattices.

Several topics concerning the light hadron spectrum are discussed. Flavor symmetry breaking effects and the problem of quenched chiral logarithm are examined with pion mass data for the Kogut-Susskind quark action, and light meson decay constants for the Wilson action calculated with non-perturbative renormalization constants are discussed. Results for quark masses are also given both for the K...

Several topics in hadron physics at different scales of resolution are discussed. First, deep-inelastic scattering from nucleons and nuclei is viewed in a light-cone coordinate space picture. Then the smooth transition from parton to hadron degrees of freedom is demonstrated by analysing generalized Q-dependent polarizabilities of the nucleon. Turning to low energy QCD we summarize recent devel...
