نویسنده
چکیده
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 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.

Preliminary results are presented in our program to calculate low moments of structure functions for the proton and neutron on a 24 3 × 32 lattice at β = 6.2. A comparison is made for a variety of smeared nucleon sources and preliminary results for the calculation of the nucleon tensor charge are presented.

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.

Based on a large number of smearing steps, we classify SU(3) gauge field configurations in different topological sectors. For each sector we compare the exact analytical predictions for the microscopic Dirac operator spectrum of quenched staggered fermions. In all sectors we find perfect agreement with the predictions for the sector of topological charge zero, showing explicitly that the smalle...
