The effect of instanton-anti-instanton interactions on current correlation functions in massless QCD

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