Abstract
We study the interaction of scalar glueball with quark–antiquark and four-quark spinless meson fields within the framework of a generalized linear sigma model in which the trace anomaly of QCD is exactly realized. To determine the pure scalar glueball mass (mh), we consider the decoupling limit in which the scalar glueball decouples from the meson fields. We find the exact relationship mh=2h0 where h0 is the vacuum expectation value of the scalar glueball field independent of the properties of the framework used. Keywords: Strong interactions, Chiral Lagrangians, Tetraquarks, Glueballs
