Abstract

We outline a comprehensive study of spin‐0 glueball properties which, in particular, keeps track of the topological gluon structure. Specifically, we implement (semi‐hard) topological instanton physics as well as topological charge screening in the QCD vacuum into the operator product expansion (OPE) of the glueball correlators. A realistic instanton size distribution and the (gauge‐invariant) renormalization of the instanton contributions are also implemented. Predictions for 0++ and 0−+ glueball properties are presented.
