Abstract :
We employ QCD sum rules, implemented with two numerical algorithms already tested in two different channels of Charmonium, in order to predict masses of resonances just above the ground states in the 3P channels. We find that such masses are above the threshold of open charm. We calculate also the partial decay widths of the ground states into light hadrons and, for even spins, into two gammas; we find consistency with data.
