Instanton density in a theory with massless quarks

Research output: Contribution to journalArticlepeer-review

216 Scopus citations


The influence of the complex structure of the QCD vacuum on the density of small-size instantons is discussed. In the theory with light quarks an expression is obtained which describes the instantons taking account of the quark vacuum condensate.
