4. 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 ???

The creation of charmed bound nuclear matter {D+n} is a real challenge. Anti-deuteron annihilation ??? Subthreshold antiproton annihilation ???

Equilibrium condition of antihydrogen with magnetic moment μ on a circular orbit with radius ρs in a toroidal sextupole field with magnetic field gradient ∂B/∂rlρs:
With the parameters of the NESTOR storage ring, ρ= 0.5 m, B=3.2 T and
∂B/∂r = 1.2 T/cm one can store antihydrogen with v= 600 m/s or equivalent
to a temperature of 21 K (!!!) which is easier to produce than required for standard traps.
