Estimate of the relation between scale parameters and the string tension by strong coupling methods
- 1. Hamburg Univ. (Germany, F.R.). 2. Inst. fuer Theoretische Physik
Description
We estimate the relation between the scale parameter Λsub(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 Λsub(L) = 3.7 x 10-3 √α. For the more conventional scale parameter Λsup(MOM) = .31 √α by use of the proportionaliy factor of Hasenfratz. Results for the string tension of Z3 lattice gauge theory are also discussed. (orig.)
