Three Loop Estimate of the Inclusive Semileptonic Decay Rate
M. R. Ahmady, F. A. Chishtie, V. Elias +4
The renormalization-scale () dependence of the two-loop inclusive semileptonic decay rate is shown to be significant in the pole mass scheme, and the de…
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…
QCD Sum-Rule Bounds on the Light Quark Masses
T. G. Steele
QCD sum-rules are related to an integral of a hadronic spectral function, and hence must satisfy integral inequalities which follow from positivity of the spectral function. Develo…
Pade Estimate of QCD's Infrared Boundary
F. A. Chishtie, V. Elias, T. G. Steele
A mass scale representing the boundary between effective theories of strong interactions and perturbative QCD (infrared and ultraviolet regimes) exists when the -function…
