Instantons and Meson Correlators in QCD

Hutter, Marcus


Various QCD correlators are calculated in the instanton liquid model in zeromode approximation and 1/N c expansion. Previous works are extended by including dynamical quark loops. In contrast to the original “perturbative” 1/N c approximation, not all quark loops are suppressed. Renormalization of the instanton density allows the identification of the density with the gluon condensate even in presence of dynamical quark loops. In the flavor singlet meson correlators a chain of quark bubbles...[Show more]
