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 …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

Visible matter is characterised by a single mass scale; namely, the proton mass. The
proton's existence and structure are supposed to be described by quantum chromodynamics …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

We discuss the QCD phase structure at finite temperature and chemical potential for 2-flavor
and 2+ 1-flavor QCD. The results are achieved by computing QCD correlation functions …

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 …

We map out the QCD phase structure at finite temperature and chemical potential for 2-
flavour and 2+ 1-flavour QCD. This is done within a generalised functional approach to QCD …

We present a comprehensive study of the quark sector of 2+ 1 flavor QCD, based on a self-
consistent treatment of the coupled system of Schwinger-Dyson equations for the quark …

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 …

We present nonperturbative first-principle results for quark, gluon, and meson 1PI correlation
functions of two-flavor Landau-gauge QCD in the vacuum. These correlation functions carry …
