Description
In this talk we will investigate the approach to the
continuum limit using different gauge actions. We will argue that
solid and precise QCD calculations need to reach lattice spacings
finer than the current standard, or that several actions need to be
consider for a proper estimate of the systematic. Flow scales for
different actions will be determined. Together with lattice
perturbation theory these can be used to extract the
pure gauge Lambda parameter from lattice quantities defined at the
scale of the cutoff.
