Finite-width effects on Delta baryons in QCD Sum Rules
G. Erkol, M. Oka
The quantum chromodynamics (QCD) sum rules for the Delta baryons are analyzed by taking into account the finite-width effects, through explicit utilization of the Breit-Wigner shap…

Scalar-Meson - Baryon Coupling Constants in QCD Sum Rules
G. Erkol, M. Oka, Th. A. Rijken +1
The external-field QCD Sum Rules method is used to evaluate the coupling constants of the light-isoscalar scalar meson (``σ'' or ε) to the Λ, Σ, and Ξbaryons. It is shown that thes…

The nucleon-sigma coupling constant in QCD Sum Rules
G. Erkol, Th. A. Rijken, R. G. E. Timmermans
The external-field QCD Sum Rules method is used to evaluate the coupling constant of the light isoscalar-scalar meson (``'' or ε) to the nucleon. The contributions that come fro…
