Abstract
Abstract We determine several quantities in quenched lattice QCD with optimal domain-wall fermion. On the 16 3 × 3 2 lattice at β = 6.0, we determine the parameters ( C , δ , B ) in the pseudoscalar meson mass in quenched chiral perturbation theory (g X PT). Using these parameters, as well as our lattice spacing a and the experimental inputs of m π and m K we determine the light quark masses: M u , d = 4.4 ± 0.3 MeV, and m s = 98 ± 7 MeV, in MS at μ = 2 GeV. Also, we determine the quark condensate 〉 q q〈 = −(250 ± 3 MeV) 3 , and the quark-gluon condensate g〉 g σ μv q〈 = −(434 ± 4 McV) 5 , in MS at scale 2 GeV.
