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...

Abstract The current data acquisition rate of astronomical transient surveys and the promise for significantly higher rates in next decade necessitate development novel approaches to analyze sets promptly detect objects interest. Deeper, Wider, Faster (DWF) program is a survey focused on identification fast-evolving transients, such as fast radio bursts, gamma-ray supernova shock breakouts. It ...

We present a lattice calculation of the leading order (LO) hadronic vacuum polarization (HVP) contribution to muon anomalous magnetic moment for connected light and strange quarks, $a^{\rm W}_{{\rm con}, l/s}$ in widely used window $t_0=0.4~\mathrm{fm}$, $t_1=1.0~\mathrm{fm}$, $\Delta=0.15~\mathrm{fm}$, also S}_{{\rm short distance region. use overlap fermions on 4 physical-point ensembles. Two...

At stronger gauge-field couplings, the domain wall fermion (DWF) residual mass (mres), a measure of chiral symmetry breaking (χSB), grows rapidly as it is largely due to near zero fermion eigenmodes of log(T ), where T is the 4D transfer matrix along the fifth dimension. The number of these eigenmodes increase rapidly at strong coupling. To suppress such near-zero eigenmodes, we have added to t...

We present RBC heavy-light meson spectroscopy with quenched DBW2 gauge configurations at lattice cutoff a−1 of about 3 GeV. Both heavy and light quarks are described by domain-wall fermions (DWF). The heavy quark mass ranges between 0.1 and 0.4 lattice units, covering charm. The light quark mass ranges between 0.008 and 0.04, covering strange. In particular, we discuss charmed (D and D) and cha...

We consider spectral quantities in lattice QCD and determine the asymptotic behavior of their discretization errors. Wilson fermion with O$(a)$-improvement, (M\"obius) Domain wall (DWF), overlap Dirac operators are considered combination commonly used gauge actions. fermions DWF domain height $M_5=1+{\rm O}(g_0^2)$ have same, approximate, form cutoff effects: $ K\,a^2\left[\bar g^2(a^{-1})\righ...

The domain wall fermion (DWF) method, with its almost perfectly preserved chiral symmetry on the lattice, makes the calculation of the nucleon axial charge particularly easy. By maintaining chiral symmetry and using the Ward-Takahashi (WT) identity, one has ZA = ZV and the bare lattice calculation yields the physical value without explicit renormalization. The DBW2 improved gauge action provide...

Objective: It was aimed to investigate whether chia seeds provide an advantage during ultrasonographic imaging in cats when added food by means of its high water-holding capacity. 
 Materials and Methods: Ten healthy were ultrasonographically examined following 12- hour fasting period after feeding with 3 different types at 1-week intervals. Thus, 4 study group formed as follows; FST; peri...

I calculate the quark-gluon vertex of the tensor type Γ(p,q) = g3(p,q)p4 / q, vector type g2(p,q)q and scalar type g1(p,q), for a small spacial momentum transfer q = q using the gauge configuration of the Domain Wall Fermion (DWF) provided by the RBC-UKQCD collaboration. The quark propagator of Coulomb gauge in the cylinder cut, i.e. the four momentum p is directed along the diagonal of the hyp...

K → π and K → 0 weak matrix elements of ∆S = 1 operators have been measured in 2+1 flavor domain wall fermion (DWF) QCD on (3 fm)3 lattices with a−1 = 1.73(3) GeV. As is well known, using these matrix elements and chiral perturbation theory allows a determination of the K → ππ matrix elements that enter in the quantitative value for the ∆I = 1/2 rule and ε ′/ε . Two light dynamical sea quark ma...
