Description

The mass spectrum and decay modes of the (cc)-(anti canti c) states are estimated in a quark-gluon model. We argue that the peculiar resonance-like structures of R(e+e- → hadrons) for √s = 6-7 GeV may be due to production of the P-wave (cc)-(anti canti c) states. They are predicted to lie in the range 6.4-6.8 GeV and mainly decay into charmend mesons. (orig.)
