We present a refined calculation of the η ′ mass using staggered fermions and Wuppertal smeared operators to suppress excited state contributions. We use quenched and dynamical configurations of size 16 3 × 32, with N f = 0, N f = 2 and N f = 4, and compare our results with the expected theoretical forms from quenched, partially quenched, and unquenched chiral perturbation theory.

We present results of a study of BK using tadpole improved gauge-invariant staggered operators. Using three ensembles of 16 3 × 32 configurations with varying numbers of dynamical flavors, we observe a small dependence on N f. Using 7 quenched ensembles at different values of β, we extrapolate to a = 0.

We report on some attempts to use lattice QCD to investigate topics in strong interaction phenomenology which are usually interpreted in terms of soft Pomeron exchange.

We present results for the spectrum and decay constants of B mesons from NRQCD using dynamical configurations at β = 5.6 with two flavours of staggered fermions. The light quarks are generated using the Clover action with tadpole improvement.
