Gluons, light and heavy quarks in the instanton vacuum

In this review we will concentrate on the nonperturbative effects in properties of hadrons made from light-heavy and heavy-heavy quarks framework Instanton Liquid Model (ILM) QCD vacuum. We briefly discuss main features ILM its applicability heavy quark sector. The gluonic systems, light correlators instanton background are also analyzed. Consideration both, perturbative nonperturbative, gluon for single lead to mass shift due direct-instanton modified contributions, respectively. For interacting quark-antiquarks, potential consists direct induced part one-gluon exchange (OGE) part. OGE interactions screened at large distances dynamics. estimations contributions phenomenological Cornell type model. As related experimental data charmonium role their spectra transitions. heavy-light systems ILM. an example, it is considering process pions emission by exited quarkonium states.
