Determination of the spin-dependent potentials with the multi-level algorithm
Miho Koma, Yoshiaki Koma, Hartmut Wittig
The spin-dependent corrections to the static interquark potential are relevant to describing the fine and hyper-fine splittings of the heavy quarkonium spectra. We investigate thes…

On the renormalized scalar density in quenched QCD
Jan Wennekers, Hartmut Wittig
We present a non-perturbative determination of the renormalization factor Z_S of the scalar density in quenched QCD with overlap fermions. Results are obtained at four values of th…
