Spectroscopy of Charmonium States Measurement of the total width and all branching widths of the charmonium states Determination of the transition probabilities Deduction of the wave functions of the states Access to non-perturbative and thus confinement effects Needs advanced QFT treatment (Weise et al.) Such a program was proposed by Bertold Stech ~ for the bottomonium system to search for non-perturbative effects. It looks even more promising for charmonium. Who does it ??? P.
