Direct Single Instanton Contributions to Finite Energy Sum Rules
A. S. Deakin, V. Elias, N. H. Fuchs +3
Instanton contributions to pseudoscalar finite-energy sum rules are extracted from the explicit single-instanton contribution to the pseudoscalar Laplace sum rule in the instanton…
QCD Sum Rules and the Pi(1300) Resonance
T. G. Steele, J. C. Breckenridge, M. Benmerrouche +2
Global fits to the shape of the first QCD Laplace sum rule exhibiting sensitivity to pion-resonance [] parameters are performed, leading to predictions for the pion-resona…
QCD Sum Rules and the Lowest-Lying I=0 Scalar Resonance
V. Elias, A. H. Fariborz, Fang Shi +1
A QCD Laplace sum rule framework is employed to investigate the relationship between the mass and the decay width of the sigma, the lowest-lying isoscalar resonance in the spin-zer…
Beyond the Narrow Resonance Approximation: Decay Constant and Width of the First Pion-Excitation State
V. Elias, A. H. Fariborz, M. A. Samuel +2
We consider the first pion excitation as a sub-continuum resonance in the pseudoscalar channel, and we obtain parameters characterizing this resonance through a global fit of the B…
