Abstract: (Elsevier)
We estimate the relation between the scale parameter Λ L and the string tension α in pure SU(3) gauge theory using strong coupling expansions for euclidean lattice gauge theory up to 12th order. The result is Λ L =3.7 × 10 −3 √ α . For the more conventional scale parameter Λ MOM this gives Λ MOM = 0.31 √ α by use of the proportionality factor of Hasenfratz. Results for the string tension of Z 3 lattice gauge theory are also discussed.
