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 review results for the phase diagram of QCD, the properties of quarks and gluons and
the resulting properties of strongly interacting matter at finite temperature and chemical …

We review the present theoretical and empirical knowledge for α s, the fundamental
coupling underlying the interactions of quarks and gluons in Quantum Chromodynamics …

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 …

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 …

The last five years have brought considerable progress in the study of the bound-state
problem in continuum quantum field theory. We highlight a subset of that progress; viz., that …

We reconstruct ghost and gluon spectral functions in 2+ 1 flavor QCD with Gaussian process
regression. This framework allows us to largely suppress spurious oscillations and other …

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

We project onto the light front the pion's Poincaré-covariant Bethe-Salpeter wave function
obtained using two different approximations to the kernels of quantum chromodynamics' …

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 …
