Universality and RG-improved gauge actions
/ Authors
/ Abstract
The reference energy scale ro is evaluated for RG-improved Iwasaki and DBW2 gauge actions (Nf = 0), at values of the deconfinement coupling ,βc, corresponding toNt = 3, 4, 6, 8. The universality ofr0Tc between Iwasaki and Wilson action is confirmed; the scaling behaviour and the influence of the violation of positivity in the extraction of effective masses are investigated.
