Exotic Mesons ande+e−Annihilation

Recent experiments at SPEAR indicate an unexpectedly large number of $1^{--}$ states in the energy range 3.9-4.4 GeV. We show how the existence of exotic $c\overline{q}\overline{c}q$ mesons can account for these states as well as the rise in $R$ and the missing $\psi \mathrm{}\left(3.7\right)\mathrm{}$ decays. The width of these states does not require that they lie above the, as yet unobserved, $D\overline{D}$ threshold. Predictions of the model are readily testable.
