Invited talk

The approach to the continuum stands as one of the main sources of uncertainty
in lattice studies. Recent investigations revealed complicated functional
forms for the lattice cutoff effects, making continuum extrapolations possibly
very difficult in practice. By using gradient flow scales we study the
continuum scaling of Yang-Mills theories using different lattice gauge actions
at the...

Invited talk

The Yang Mills Gradient Flow is frequently used in lattice QCD and lattice pure gauge theory with particular focus on precision scale-setting. Other uses include, e.g., (non-perturbative) operator renormalisation and so called smearing.
Aiming at precision physics, all systematics must be kept under good control. I will focus here on the lattice artifacts relevant when attempting continuum...
