Abstract

We study the instanton-induced effects on the propagators of light quarks, using the pseudoparticle ensemble obtained previously. It is shown how massless quarks develop some effective mass as they "jump" from one instanton to another. Correlation functions for mesons made of a light quark and a very heavy anti-quark are also calculated, the results are in good agreement with the available experimental data.
