Query: Precision determination of r_0Lambda_MS from the QCD static energy   We use the recently obtained theoretical expression for the complete QCD
static energy at next-to-next-to-next-to leading-logarithmic accuracy to
determine r_0Lambda_MS by comparison with available lattice data, where r_0 is
the lattice scale and Lambda_MS is the QCD scale. We obtain
r_0Lambda_MS=0.637^{+0.032}_{-0.030} for the zero-flavor case. The procedure we
describe can be directly used to obtain r_0Lambda_MS in the unquenched case,
when unquenched lattice data for the static energy at short distances becomes
available. Using the value of the strong coupling alpha_s as an input, the
unquenched result would provide a determination of the lattice scale r_0.
