Universality and RG-improved gauge actions

Abstract
The reference energy scale r_0 is evaluated for RG-improved Iwasaki and DBW2 gauge actions (N_f = 0), at values of the deconfinement coupling beta_c corresponding to N_t = 3,4,6,8. The universality of r_0 T_c between Iwasa ki and Wilson action is confirmed; the scaling behaviour and the influence of th e violation of positivity in the extraction of effective masses are investigated.
