Query: Comparing the QCD potential in Perturbative QCD and Lattice QCD at large
  distances   We compare the perturbatively calculated QCD potential to that obtained from
lattice calculations in the theory without light quark flavours. We examine
E_tot(r) = 2 m_pole + V_QCD(r) by re-expressing it in the MSbar mass m =
m^MSbar(m^MSbar) and by choosing specific prescriptions for fixing the scale mu
(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*r_0 ~ 7.5 GeV^-1 (r_0 is the Sommer scale) within the uncertainty of order
Lambda^3 r^2.
