Excited Charmonium Decays by Flux-Tube Breaking and the Anomaly at CDF
The hadronic decay of radially and orbitally excited charmonium above charm
threshold by pair creation and chromoelectric flux--tube breaking is
discussed in an harmonic oscillator approximation. We find independent evidence
from a study of widths for a 2S admixture in the predominantly 1D state
, and explore the possibility of metastable radially excited 2 \;
^{3}P_{0,1,2} states being a source of the anomalously large production of
at the Tevatron. At least one of them is expected to be narrow as a
consequence of the existence of nodes in the radial wave function.Comment: 18 pages, LaTeX, 5 tables, 3 postscript figures, with minor
