Abstract
The leading order effects, away from the Dilute Gas Approximation, of instanton-antiinstanton interactions are studied in massless QCD. Propagation and current correlation functions are computed in the interacting dilute gas. While no mass is generated, power law corrections are achieved for the correlation function entering intoe + e − annihilation.
