The influence of gauge field smearing on discretisation effects

Andreas Risch, Stefan Schaefer, Rainer Sommer

When designing lattice actions, gauge field smearing is frequently used to define the lattice Dirac operator. Since the smearing procedure removes effects of ultraviolet fluctuatio…

Learning Trivializing Gradient Flows for Lattice Gauge Theories

Simone Bacchio, Pan Kessel, Stefan Schaefer +1

We propose a unifying approach that starts from the perturbative construction of trivializing maps by Lüscher and then improves on it by learning. The resulting continuous normaliz…

Scale Setting for CLS 2+1 Simulations

Ben Straßberger, Marco Cè, Sara Collins +9

We present an update of the scale setting for flavor QCD using gradient flow scales and pseudo-scalar decay constants. We analyze the latest ensembles with flavors…

Remarks on strange-quark simulations with Wilson fermions

Daniel Mohler, Stefan Schaefer

In the simulation of QCD with 2+1 flavors of Wilson fermions, the positivity of the fermion determinant is generally assumed. We present evidence that this assumption is in general…

Frequency-splitting estimators for single-propagator traces

Leonardo Giusti, Tim Harris, Alessandro Nada +1

In these proceedings we address the computation of quark-line disconnected diagrams in lattice QCD. The evaluation of these diagrams is required for many phenomenologically interes…

Frequency-splitting estimators of single-propagator traces

Leonardo Giusti, Tim Harris, Alessandro Nada +1

Single-propagator traces are the most elementary fermion Wick contractions which occur in numerical lattice QCD, and are usually computed by introducing random-noise estimators to…
