Optimal RG-Improvement of Perturbative Calculations in QCD
V. Elias
Using renormalization-group methods, differential equations can be obtained for the all-orders summation of leading and subsequent non-leading logarithmic corrections to QCD pertur…
The Infrared Boundary of Perturbative QCD
Victor Elias
Evidence is reviewed suggesting that QCD remains a perturbative theory with a (relatively) small coupling constant down to a distinct infrared boundary on perturbative physics, a b…
Probing the Infrared Structure of Gauge Theories: A Pade-Approximant Approach
F. A. Chishtie, V. Elias, V. A. Miransky +1
Pade-approximant treatments of the known terms of the QCD -function are seen to develop possible infrared fixed point structure only if the number of fermion flavours is suffici…
QCD Sum-Rule Invisibility of the sigma Meson
T. G. Steele, Fang Shi, V. Elias
QCD Laplace sum-rules for light-quark I=0,1 scalar currents are used to investigate candidates for the lightest scalar mesons. The theoretical predictions for the sum-rul…
Fermion-Antifermion Condensate Contribution to the Anomalous Magnetic Moment of a Fundamental Dirac Fermion
Victor Elias, Kevin Sprague
We consider the contribution of fermion-antifermion condensates to the anomalous magnetic moment of a fermion in a vacuum in which such condensates exist. The real part of the cond…
Pade Approximants and the Fixed-Points of the three-flavour QCD beta-Function
V. Elias, T. G. Steele
The positive zeros of [2|1], [1|2] and the most general possible [2|2] Pade approximants whose Maclaurin series reproduce the presently known terms in the three-flavour QCD beta-fu…
