Power-law corrections to the quantum chromodynamics sum rules for charmonium
The calculated 0{G4) power-law corrections to the quantum chromodynamics sum rules for charmonium in the Jpc ~ 1 channel are discussed. Under the standard assumptions regarding the structure of the quantum chromodynamics vacuum, the incorporation of these corrections radically changes the shape of the theoretical curve for the ratio rn, which is used in analyzing the low-lying states of charmonium by the quantum-chromodynamics sum-rule method.
