Melville: Amer Inst Physics, v. 739, p. 434-436, 2004.0094-243Xhttp://hdl.handle.net/11449/23411We 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.434-436engQCD vacuum topology and glueballsTrabalho apresentado em evento10.1063/1.1843614WOS:000226476000024Acesso aberto
