The authors have performed a search for a charged partner of the X(3872) decaying to J/[psi][pi][sup [+-]][pi][sup 0]. The results set upper limits on the product branching fractions of B([bar B][sup 0]/B[sup 0] --> X[sup [+-]]K[sup [-+]], X[sup [+-]] --> J/[psi][sup [+-]][pi][sup 0]) 5.2 x 10[sup -6] and B(B[sup [+-]]) -- X[sup [+-]]K[sup 0][sub s], X[sup [+-]] --> J/[psi][sup [+-]][pi][sup 0]

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]−, i.e. the Z(4430)− 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)−.

We present results of a search for the X(3872) in B° → X(3872)K{sub S}°, X(3872) → J/???−, improved measurements of B− → X(3872)K−, and a study of the J/??+?− mass region above the X(3872). We use 232 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II e+e− asymmetric-energy storage rings. The results include the 90% confidence interval 1.34 x 10−6

We present a measurement of the branching fraction for the decay of the neutral B meson into the final state J/[psi][pi][sup+][pi][sup -]. The data set contains approximately 56 million B[bar B] pairs produced at the[Upsilon](4S) resonance and recorded with the BABAR detector at the PEP-II asymmetric-energy e[sup+]e[sup -] storage ring. The result of this analysis is[Beta](B[sup 0][yields] J/[psi][pi][sup+][pi][sup -])= (4.6[+-] 0.7[+-] 0.6) x 10[sup -5], where the first error is statistical and the second is systematic. In addition we measure[Beta](B[sup 0][yields] J?[psi][rho][sup 0])= (1.6[+-] 0.6[+-] 0.4) x 10[sup -5].

The authors report the observation of a narrow state decaying into J/???− and produced in 220 pb−1 of {bar p}p collisions at √s = 1.96 TeV in the CDF II experiment. They observe 730 ± 90 decays. The mass is measured to be 3871.3 ± 0.7(stat) ± 0.4(syst) MeV/c2, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.
