Hadron structure from the lattice

Lattice calculations are used to show the dominant role of instantons in determining light hadron structure and quark propagation in the QCD vacuum. The instanton content of gluon fields sampling the Wilson action is extracted using cooling as a filter to selectively remove essentially all fluctuations of the gluon field except for instantons. Close agreement is demonstrated between quenched lattice QCD results including all gluonic contributions and including only instantons for vacuum correlation functions of hadronic currents and for density-density correlation functions in hadronic bound states. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
