We present results of a search for the X(3872) in B0→X(3872)KS0, 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 BB̄ pairs collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+e- asymmetric-energy storage rings. The results include the 90% confidence interval 1.34×10-6

Abstract

We present results of a search for the X(3872) in B0→X(3872)KS0, 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 BB̄ pairs collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+e- asymmetric-energy storage rings. The results include the 90% confidence interval 1.34×10-6
