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 meson masses and decay constants in 2 + 1 flavour domain wall QCD
We present results for light meson masses and psedoscalar meson decay constants in 2+1 flavour domain wall QCD with the DBW2 and Iwasaki gauge actions, using lattices with linear sizes in the range 1.6 to 2.2fm and u and d quark masses as low as one quarter of the strange quark mass. All data were generated on the QCDOC machines at the University of Edinburgh and Brookhaven National Laboratory....
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...
متن کاملStatic-light meson masses from twisted mass lattice QCD
We compute the static-light meson spectrum using two-flavor Wilson twisted mass lattice QCD. We have considered five different values for the light quark mass corresponding to 300 MeV < ∼ m PS < ∼ 600 MeV. We have extrapolated our results, to make predictions regarding the spectrum of B and B s mesons.
متن کاملConstraints on light quark masses from the heavy meson spectrum.
We use the observed SU(3) breaking in the mass spectrum of mesons containing a single heavy quark to place restrictions on the light quark current masses. A crucial ingredient in this analysis is our recent first-principles calculation of the electromagnetic contribution to the isospin-violating mass splittings. We also pay special attention to the role of higher-order corrections in chiral per...
