Abstract: (APS)

The picture that charmed quarks are interacting with each other through a linear potential is used to analyze the particle spectrum in the high-energy annihilation process e+e−→hadrons. With the newly found resonances at 3.1 and 3.7 GeV as input, we predict other resonances (in particular, one at approximately 4.0 GeV) and determine the hadronic width of the 3.1 and leptonic widths of the 3.1 and 3.7 resonances. Extending the linear potential to quarks without charm enables us to predict the charmed-particle threshold to be approximately 5 GeV.
