2. Perfect lattice actions for SU(3) gauge theory

Liane Backfried (Universität Bern)

Perfect lattice actions are renormalization-group improved actions that share their low energy properties with the continuum theory. This allows us to recover continuum physics even from very coarse lattices, with lattice artifacts being absent or at least notably suppressed. The difficulty in employing such actions in simulations is finding a suitable parameterization: in principle, they are...
