Abstract: (Elsevier)
We estimate the location β R = ( g R 2 N ) −1 of the recently discussed roughening transition for SU( N ) lattice gauge theories in ν = 3 and 4 dimensions. The obtained values always lie in the crossover region where the string tension starts to deviate significantly from the leading strong coupling behaviour. β R ( N ) increases as N increases, tending to a finite limit (≈0.38 for ν = 4) as N → ∞. Results for the solid on solid model (SOS) approximation are also presented and shown to give a good qualitative description; however, group theoretical effects seem to be important for quantitative estimates.
