چکیده
We present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performed using RBC–UKQCD’s Nf = 2 + 1 domain wall fermion ensembles with physical light sea quark masses at two lattice spacings. We consider a large number of analysis scenarios in order to obtain solid estimates for residual systematic effects. Our final result in the continuum limit is a (2) had, s μ = 53.1(9) ( +1 −3 ) × 10−10. ar X iv :1 60 2. 01 76 7v 2 [ he pla t] 1 8 M ar 2 01 6

Domain Wall Fermion simulations by the RBC and UKQCD collaborations
We review simulations of dynamical domain wall fermions at a fixed inverse lattice spacing of 1.73GeV and with pion masses as light as 330MeV and spatial dimensions as large as 2.7fm performed by the RBC and UKQCD collaborations. These results include pseudoscalar masses and decay constants and low energy constants of the chiral effective lagrangian. We also review results for the neutral kaon ...

We present results for the couplings of light vector mesons to vector and tensor currents and on the low moments of the light-cone distribution amplitudes of the pion and kaon. The calculations are performed on the RBC and UKQCD collaborations’ ensembles generated with the Iwasaki gauge action and with 2+1 flavours of domain wall fermions. The (preliminary) results for the ratios of the couplin...
متن کاملThe static quark potential for dynamical domain wall fermion simulations
We present preliminary results for the static quark potential computed on some of the DWF lattice configurations generated by the RBC-UKQCD collaborations. Most of these results were obtained using Wilson lines joining spatial planes fixed into the Coulomb gauge. We compare the results from this method with the earlier ones on 163 × 32 lattices using Bresenham spatial paths with APE smeared lin...
متن کاملIsospin symmetry breaking effects in the pion and nucleon masses
We investigate the electromagnetic mass splittings in the pseudoscalar meson and nucleon systems by combining 2+1 flavor domain wall fermion gauge configurations, generated by the RBC and UKQCD collaborations, and quenched, non-compact, lattice QED configurations. We analyze finite volume effects by using 16 3 × 32 and 24 3 × 64 lattices. Isospin symmetry breaking effects in the pion and nucleo...
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 کاملCharmed spectroscopy from a nonperturbatively determined relativistic heavy quark action in full QCD
We present a preliminary calculation of the charmed meson spectrum using the 2+1 flavor domain wall fermion lattice configurations currently being generated by the RBC and UKQCD collaborations. The calculation is performed using the 3-parameter, relativistic heavy quark action with nonperturbatively determined coefficients. We will also demonstrate a step-scaling procedure for determining these...
