BK from Two-flavor Dynamical Domain Wall Fermions
نویسنده
چکیده
We report preliminary results from an ongoing calculation of BK for Nf = 2 dynamical QCD with domain wall fermions. Simulations have been done with three dynamical quark masses on 16 × 32 volumes with Ls = 12, where the lattice spacing is a = 1.81(6) GeV. Using measurements on ∼ 70 lattices for each dynamical mass and extrapolating mdyn = mval to the kaon point, we find B MS K (μ = 2GeV) = 0.503(20).

Dynamical lattice QCD thermodynamics with domain wall fermions
We present results from simulations of two flavor QCD thermodynamics at Nt = 4 with domain wall fermions. In contrast to other lattice fermion formulations, domain wall fermions preserve the full SUL(Nf )⊗ SUR(Nf) symmetry of the continuum at finite lattice spacing (up to terms exponentially small in an extra parameter). Just above the phase transition, we find that the UA(1) symmetry is broken...

We report on the first large-scale study of two flavor QCD with domain wall fermions (DWF). Simulation has been carried out at three dynamical quark mass values about 1/2, 3/4, and 1 mstrange on 16 3 × 32 volume with Ls = 12 and a −1 ≈ 1.7 GeV. After discussing the details of the simulation, we report on the light hadron spectrum and decay constants.
متن کاملChiral Symmetry Restoration in the Schwinger Model with Domain Wall Fermions
Domain Wall Fermions utilize an extra space time dimension to provide a method for restoring the regularization induced chiral symmetry breaking in lattice vector gauge theories even at finite lattice spacing. The breaking is restored at an exponential rate as the size of the extra dimension increases. Before this method can be used in dynamical simulations of lattice QCD, the dependence of the...
متن کاملThe Kaon B-parameter from Two-flavour Dynamical Domain Wall Fermions
We report on the calculation of the kaon B-parameter using two dynamical flavours of domain wall fermions. Our analysis is based on three ensembles of configurations, each consisting of about 5,000 HMC trajectories, with a lattice spacing of approximately 1.7 GeV for 16 3 ×32 lattices; dynamical quark masses range from approximately the strange quark mass to half of that. Both degenerate and no...
متن کاملStaggered Domain Wall Fermions
Staggered Domain Wall Fermions (SDWF) combine the attractive chiral properties of staggered fermions with those of domain wall fermions. SDWF describe four flavors with exact U(1)×U(1) flavor chiral symmetry. An extra lattice dimension is introduced and the full SU(4)×SU(4) flavor chiral symmetry is recovered as its size is increased. Here, the free theory of SDWF is described and a preliminary...
