We present an update of the study of the Y(4260) resonance, produced in the process ee− →?{sub ISR}?+?− J/? using initial-state radiation events at the PEP-II e+e− storage rings. This study is based on 454 fb−1 of data recorded with the BABAR detector at a center-of-mass energy in the?(4S) resonance region. From a fit with a single non-relativistic Breit-Wigner shape we obtain updated parameters for the Y(4260) resonance which are m{sub Y} = 4252 ± 6−3{sup +2} MeV/c2 and?{sub Y} = 105 ± 18−6{sup +4} MeV/c2; we also measure?(?+?− J/?)?{sub e{sup +}e−} = (7.5 ± 0.9 ± 0.8) eV. We cannot confirm the recent BELLE observation of a broad structure around 4.05GeV/c2 in this decay mode.

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
