| Abstract: | Symanzik one-loop and block-spin renormalization group improved actions are studied by Monte Carlo simulation. Scaling sets in at small correlation length for the considered actions. The approach to the continuum relativistic energy-momentum dispersion is best for Symanzik one-loop improved action. |
