A note on Rome-Southampton Renormalization with Smeared Gauge Fields

Understand

We have calculated continuum limit step scaling functions of bilinear and four-fermion operators renormalized in a Rome-Southampton scheme using various smearing prescriptions for the gauge field.

• Also, for the first time, we have calculated non-perturbative anomalous dimensions of operators renormalized in a Rome-Southampton scheme.
• The effect of such smearing first enters connected fermionic correlation functions via radiative corrections.
• We use off-shell renormalisation as a probe, and observe that the upper edge of the Rome-Southampton window is reduced by link smearing.
