domain-wall light quark system
نویسنده
چکیده
We discuss the perturbative O(αsa) matching in the static heavy and domain-wall light quark system. The gluon action is the Iwasaki action and the link smearing is performed in the static heavy action. The chiral symmetry of the light quark realized by using the domain-wall fermion formulation does not prohibit the mixing of the operators at O(a). The application of O(a) improvement to the actual data shows that the B meson decay constant fB, the matrix elements MB and the B parameter BB have non-negligible effects, while the effect on the SU(3) breaking ratio ξ is small.

Light Quark Masses Using Domain Wall Fermions *
We compute the one–loop self–energy correction to the massive domain wall quark propagator. Combining this calculation with simulations at several gauge couplings, we estimate the strange quark mass in the continuum limit. The perturbative one–loop mass renormalization is comparable to that for Wilson quarks and considerably smaller than that for Kogut–Susskind quarks. Also, scaling violations ...
متن کاملLight Quark Masses from Quenched Lattice Qcd Simulations with Domain Wall Quarks∗
The light quark masses are fundamental parameters of the Standard Model and, as such, must be determined more precisely in order to increase its predictive power. Lattice QCD can play an important role in computing the quark masses, as it already has with the strong coupling constant. Recently it was shown that the new domain wall fermion discretization can be applied to this endeavor. This tal...
متن کاملMassive Domain Wall Fermions on Four-dimensional Anisotropic Lattices
We formulate the massive domain wall fermions on anisotropic lattices. For the massive domain wall fermion, we find that the dispersion relation assumes the usual form in the low momentum region when the bare parameters are properly tuned. The quark self-energy and the quark field renormalization constants are calculated to one-loop in bare lattice perturbation theory. This calculation serves a...
متن کاملBaryons in 2 + 1 flavour domain wall QCD
Preliminary results for some of the light baryon masses and their excited states in 2+1 flavour domain wall QCD are presented. The spectrum was determined on two volumes, 16 3 × 32 and 24 3 × 64, both with L S = 16. The degenerate light quark mass is less than a third of the strange quark mass. All data was produced jointly by the RBC and UKQCD collaborations on QCDOC machines.
متن کاملLight quark masses from Domain Wall Fermions
We present results for the renormalised light and strange quark masses calculated using Domain Wall Fermions in quenched QCD. New results using the DBW2 gauge action at a ≈ 2GeV and a ≈ 1.3GeV will be presented and compared against existing results at a ≈ 2GeV using the Wilson gauge action. This comparison allows a study of the uncertainties due to both finite lattice spacing and residual chira...
