摘要：

We present a comprehensive study of finite volume and lattice spacing effects on observables calculated in the static approximation. Ground state projection using smearing techniques is studied at beta = 6.26. We give high statics results for the pseudoscalar decay constant after extrapolating to the chiral and continuum limit. In addition results for mass splittings and the distance of string breaking in the QQBAR potential are presented.
