摘要：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 mixing amplitude BK, the Kl3 form factor, pseudoscalar meson structure, and vector meson decay constants. In the baryon sector we review results for the spectrum, and nucleon form factors and structure functions. Highlights of our programme include preliminary quark masses, and determinations of Vus from both fK/ fp and from Kl3, and an updated result for BK. We find significant finite volume effects in the nucleon axial charge gA for our mp = 330 MeV ensemble on a (2.7fm)3 lattice, and highlight the importance of large physical volumes for non-trivial nucleon physics.
