The authors search for a charged partner of the X(3872) in the decay B → X−K, X− → J/??−?°, using 234 million B{bar B} events collected at the?(4S) resonance with the BABAR detector at the PEP-II ee− asymmetric-energy storage ring. The resulting product branching fraction upper limits are?(B° → X−K+, X− → J/??−?°)

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

The BABAR Collaboration performed a search for x (2220) production in the initial-state radiation process ee− →? J/?, J/? →?K+K− or J/? →?K{sub S}°K{sub S}°. No evidence for the? (2220) resonance has been found. The 90% confidence level upper limits on the product of branching fractions are sensitive to the spin and helicity hypotheses. These upper limits are of the order 10−5, below the values reported in previous experiments. Also at BABAR, the decays B → J/??+?−?°K are studied to search for the decay X(3872) → J/??. This search yields a four standard deviation evidence for X(3872) → J/??, with product branching fractions of?(B+ → X(3872)K+) x?(X(3872) → J/??) = [0.6 ± 0.2(stat) ± 0.1(syst)] x 10−5, and?(B° → X(3872)K°) x?(X(3872) → J/y?) = [0.6 ± 0.3(stat) ± 0.1(syst)] x 10−5. A detailed study of the?+?−?° mass distribution from X(3872) decay favors a negative-parity assignment but does not rule out the positive-parity hypothesis.
