Nonperturbative properties of Yang-Mills theories

Understand

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 elementary particles, the gauge bosons.
• In quantum chromodynamics, the correlation functions of the gluons are basic ingredients for calculations of hadrons from bound state equations or properties of its phase diagram with functional methods.
• Correlation functions of gluons are defined only in a gauge fixed setting.
