Abstract

We compare the perturbatively calculated QCD potential to that obtained from lattice calculations in the theory without light quark flavours. We examine Etot(r) = 2mpole + VQCD(r) by re-expressing it in the MS mass m ≡ mMS(mMS) and by choosing specific prescriptions for fixing the scale μ (dependent on r and m). By adjusting m so as to maximise the range of convergence, we show that perturbative and lattice calculations agree up to 3 r0 ≃ 7.5 GeV-1 (r0 is the Sommer scale) within the uncertainty of order ΛQCD3 r2.
