Gaussian Sum-Rules, Scalar Gluonium, and Instantons
T. G. Steele, D. Harnett, G. Orlandini
Gaussian sum-rules relate a QCD prediction to a two-parameter Gaussian-weighted integral of a hadronic spectral function, providing a clear conceptual connection to quark-hadron du…

Two Topics in QCD Sum-Rules: Bounds on Light Quark and Scalar Gluonium Masses
T. G. Steele, D. Harnett
QCD Laplace sum-rules are briefly reviewed and two sum-rule applications are presented. For scalar gluonium, upper bounds on the lightest state are obtained from ratios of Laplace…
