The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

We discuss our present knowledge of α s, the fundamental running coupling or effective
charge of Quantum Chromodynamics (QCD). A precise understanding of the running of α s …

We investigate Landau gauge SU (3) Yang-Mills theory in a systematic vertex expansion
scheme for the effective action with the functional renormalization group. Particular focus is …

The dynamics of the QCD gauge sector give rise to non-perturbative phenomena that are
crucial for the internal consistency of the theory; most notably, they account for the …

Abstract Emergent Hadron Mass (EHM) is a mechanism capable of explaining both the
unnaturally small (pion) and large (proton) masses of hadrons and if not the origin of …

Using lattice configurations for quantum​​​​​ chromodynamics (QCD) generated with
three domain-wall fermions at a physical pion mass, we obtain a parameter-free prediction …

Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

It is currently widely accepted that gluons, while massless at the level of the fundamental
QCD Lagrangian, acquire an effective mass through the non-Abelian implementation of the …

Lattice simulations of the QCD correlation functions in the Landau gauge have established
two remarkable facts. First, the coupling constant in the gauge sector—defined, eg, in the …

Correlation functions of Yang-Mills theory in the Landau gauge are calculated from their
equations of motion. The employed setup is completely parameter free and leads, within …
