Lattice QCD with domain wall quarks and applications to weak matrix elements
Using domain wall fermions, we estimate BK(μ ≈ 2 GeV) = 0.628(47) in quenched QCD which is consistent with previous calculations. At 6/g = 6.0 and 5.85 we find the ratio fK/mρ in agreement with the experimental value, within errors. These results support expectations that O(a) errors are exponentially suppressed in low energy (E a) observables, and indicate that domain wall fermions have good s...

Using domain wall fermions, we estimate BK (µ ≈ 2 GeV) = 0.628(47) in quenched QCD which is consistent with previous calculations. At 6/g 2 = 6.0 and 5.85 we find the ratio fK /mρ in agreement with the experimental value, within errors. These results support expectations that O(a) errors are exponentially suppressed in low energy (E ≪ a −1) observables, and indicate that domain wall fermions ha...
متن کاملLattice QCD with dynamical domain wall quarks
An obvious source of systematic error in numerical lattice QCD at present is the quenched approximation. Use of domain wall fermion (DWF) [1] dynamical quarks to lift this approximation is attractive because DWF preserve the flavor and chiral symmetries both on and off shell on the lattice before the continuum limit is taken. Evidently successful implementation would bring many advantages, such...
متن کاملDomain wall quarks and kaon weak matrix elements
We present lattice calculations of kaon matrix elements with domain wall fermions. Using lattices with 6/g2 = 5.85, 6.0, and 6.3, we estimate BK(μ ≈ 2 GeV) = 0.628(47) in quenched QCD which is consistent with previous calculations. At 6/g2 = 6.0 and 5.85 we find the ratio fK/mρ in agreement with the experimental value, within errors. These results support expectations that O(a) errors are expon...
متن کامل1505 : Update on lattice QCD with domain wall quarks
Using domain wall fermions, we estimate BK(μ ≈ 2 GeV) = 0.602(38) in quenched QCD which is consistent with previous calculations. We also find ratios of decay constants that are consistent with experiment, within our statistical errors. Our initial results indicate good scaling behavior and support expectations that O(a) errors are exponentially suppressed in low energy (E a) observables. It is...
