THE STATIC POTENTIAL IN FULL QCD - A PRECISE DETERMINATION

We present a lattice calculation of the interquark potential between s tatic quarks in a ''full'' QCD simulation with 2 flavours of dynamical Wilson-quarks at three intermediate sea-quark masses. We work at beta = 5.6 on a lattice size of 16(3) x 32 with 100 configurations per sea -quark mass. We compare the full QCD potential with its quenched count erpart at equal lattice spacing, a(-1) similar or equal to 2.0 GeV, wh ich is at the onset of the quenched scaling regime. We find that the f ull QCD potential lies consistently below that of quenched QCD. We see no evidence for string-breaking effects on these lattice volumes, V s imilar or equal to(1.5 fm)(3).
