I will give a historical account of the development from the invention of quarks, via the detection of partons and subsequent ideas on hadron physics until the creation of quantum chromodynamics.
Hadrons have been the focus of much interest in the past 50 years. The challenges of Poincaré covariance and color confinement have been addressed by various methods, including QCD theory, numerical (lattice) and model approaches. We have considerable experience with atoms and molecules. Yet the bound state principles of Quantum Field Theory are not found in textbooks.
The bound state...
I will review classical chiral symmetries of QCD
and a new chiral spin symmetry, which is a symmetry
of the confining electric part of QCD. I will discuss
implication of these symmetries for hadrons and for QCD

I will review the main achievements in hadronic physics that have been gained along constituent-quark models over about 50 years, since the creation of quantum chromodynamics. In particular, I will show that the modern relativistic constituent-quark model serves as a good effective approach to a unified description of hadron physics in the low-energy regime. There the relevant degrees of...
In the non-perturbative regime QCD generates the masses and internal structure of the hadrons. At the deepest level it is also responsible for the structure of atomic nuclei. In this brief review we will examine some of the historical highlights in this development, as well as exciting open questions.
A survey is given on the current status of the theoretical description of unpolarized and polarized deep–inelastic scattering processes in Quantum Chromodynamics at large virtualities.
Chiral symmetry of QCD plays a key role in understanding the properties of nuclear interactions and low-energy physics of atomic nuclei. Its implications for nuclear structure and dynamics can by analyzed in a systematic way using the framework of chiral effective field theory. I will briefly describe conceptual foundations of this method, review our recent efforts towards developing it into a...
Hadrons, known to be the effective degrees of freedom of “strong" interactions, that emerge from the fundamental degrees of freedom (quarks and gluons) at the low-energy scales demand nonperturbative approaches for an understanding from first principles. In this talk, I will discuss how the composition of the hadron spectrum can be studied using numerical simulations of Quantum Chromo-...
Lattice QCD has recently seen theoretical and computational advancements. These developments are allowing us to both compute hadron structure to unprecedented accuracy and to explore quantities that were thought impossible to calculate within lattice QCD for many years. In the first category belong hadrons charges and form factors and higher Mellin moments that can shed light on spin...
