An exploratory study of the low-lying eigenvalues of the Wilson-Dirac operator and their corresponding eigen-vectors is presented. Results for the eigenvalues from quenched and unquenched simulations are discussed. The eigenvectors are studied with respect to their localization properties in the quenched approximation for the cases of SU(2) and SU(3).

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.

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.

Starting from the meson-meson Green function in 3+1 dimensional quenched lattice QCD we calculate potentials between heavy-light mesons for various light-quark mass parameters. For the valence quarks we employ the staggered scheme. The resulting potentials turn out to be short ranged and attractive. A comparison with a tadpole improved action for the gauge fields is presented.

The Hybrid Monte Carlo (HMC) algorithm[1] is now the standard method to simulate dynamical fermions. However the cost of the algorithm is substantial. It is therefore desirable to improve the efficiency of the HMC algorithm. First, we examine the possibility of changing the step size adaptively[2,3]. Second, we implement the HMC algorithm with approximate Hamiltonians. Lastly, we precondition t...
