Description
QCD has a rich spectrum that encompasses bound states of different types. In pure Yang–Mills theory the spectrum consists of glueballs, which are also expected to be realized in the presence of quarks. The former theory provides a clean theoretical setup in which the spectrum has been established by various methods, including functional equations. In a top‑down approach, these equations provide a framework that does not require external model input. To progress toward full QCD, the existing solutions for gluonic correlation functions are used as a basis for including quarks. Particular attention is paid to constructing a truncation that respects chiral symmetry so that it can be applied to light mesons.
