چکیده

We report the details of our ongoing quenched calculations of weak matrix elements using the combination of domain-wall fermions and the DBW2 gauge action on lattices with a −1 ≈ 3 GeV. A strategy to avoid the problem of fixed topological charge is introduced in generating gauge configurations. After studying the basic run parameters and elemental quantities, we present a preliminary result for the kaon B-parameter (BK).

We present calculations of the decay constants and kaon B-parameter BK as the first stage of RBC Collabo-ration's quenched numerical simulations using DBW2 gauge action and domain-wall fermions. Some of potential systematic errors and consistency to previous works are discussed.

The techniques of lattice gauge theory offer the possibility of accurate, non-perturbative calculation of the masses and matrix elements predicted by low-energy QCD. Of particular interest are the properties of the K-meson system and the lowenergy, weak matrix elements that are required to understand Kaon decays, especially those which enter the K → ππ amplitudes which violate CP symmetry. Pres...

We present a preliminary domain-wall fermion lattice-QCD calculation of isovector vector and axial charges, g V and g A , of the nucleon. Since the lattice renormalizations, Z V and Z A , of the currents are identical with DWF, the lattice ratio (g A /g V ) directly yields the continuum value. Indeed Z V determined from the matrix element of the vector current agrees closely with Z A from a non...

The action of Weyl scale invariant p=3 brane (domain wall) which breaks the target super Weyl scale symmetry in the N=1, 5D superspace down to the lower dimensional Weyl symmetry W (1, 3) is derived by the approach of coset method. Its dual form action for the Weyl scale invariant tensor gauge field theory is also constructed.
