We present results of a search for the X(3872) in B0→X(3872)K0S,X(3872)→J/ψπ+π−, improved measurements of B−→X(3872)K−, and a study of the J/ψπ+π− mass region above the X(3872). We use 232×106 B¯¯¯B pairs collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+e− asymmetric-energy storage rings. The results include …
