OSTI ID:1029896
Recently, several charmonium-like states above D{bar D} threshold have been discovered at the BELLE and BABAR B-factories. Some of these states are produced via Initial State Radiation (e.g. Y (4260) and Y (4350)) and some are observed in B meson decays (e.g. X(3872), Y (3940)). The BELLE observation of the enhancement in the {psi}(2S){pi}{sup -}, i.e. the Z(4430){sup -} state, has generated a great deal of interest, because such a state must have minimum quark content (c{bar c}d{bar u}), so that it would represent the unequivocal manifestation of a four-quark meson state. Here we report recent BABAR results on the Y (4260), X(3872), Y(3940), and a search for the Z(4430){sup -}.
