Fundamental parameters from QCD sum rules: S-wave charmonium
Description
We re-examine QCD sum rules for S-wave charmonium. Dimension 6, 8 contributions for both 3S1, 1S0 waves are taken into account using the factorisation model and found to be reasonably small. A good fit to the data requires the confinement paramter Φ, to be much bigger than the generally accepted value. (orig.)
