Qcd Sum Rules and the Lowest-lying I = 0 Scalar Resonance

  • A. H. Fariborz

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-zero meson channel. Our analysis differs from prior analyses, not only by incorporating finite-width departures from the narrow resonance approximation , but also through the… (More)
