Abstract
A simulation of the SU(2) theory at finite temperatures by means of a Symanzik improved action is presented. The asymptotic scaling properties are discussed, based on an accurate measurement of the deconfinement temperature. The asymptotic scaling violation pattern is found to be substantially equivalent to the one already observed in studies using the Wilson action. An analysis using an effective coupling shows a precocious scaling, which we interpret as an effect of the Symanzik improvement.File in questo prodotto:
