Abstract

We compute, for the four-dimensional SU(4) and SU(6) gauge theories formulated on a lattice, the string tensions sigma_k related to sources with Z_N charge k, using Monte Carlo simulations. Our results are compatible with sigma_k ∝ sin (k pi/N), and show sizeable deviations from Casimir scaling.
