The screening of colour charge in the numerical hopping-parameter expansion
Abstract
The screening of the quark-antiquark potential by dynamical quark-antiquark pairs is numerically investigated in SU(2) colour gauge theory with Wilson fermions. The expected qualitative behaviour is born out by a high-order hopping-parameter expansion. The screening length is about 0.8 fm and the dissociation energy of a heavy quark-antiquark pair is near 600-800 MeV.
