Description
We report about an ongoing non-perturbative computation of RI-MOM scheme renormalization constants for
the lattice action with Iwasaki glue and four dynamical flavours currently in use by ETMC.
For this goal dedicated simulations with four degenerate sea quark flavours
are performed at several values of the standard and twisted quark mass parameters. We discuss a
method for removing possible O(a) artifacts at all momenta and extrapolating renormalization
constant estimators to the chiral limit. We give preliminary results at one lattice spacing.
