Abstract

We search for a charged partner of the X(3872) in the decay B\ensuremath→X^\ensuremath-K, X^\ensuremath-\ensuremath→J/\ensuremathψ\ensuremathπ^\ensuremath-\ensuremathπ⁰, using 234\ifmmode×\else\texttimes\fi10⁶ BB events collected at the \ensuremathΥ(4S) resonance with the BABAR detector at the PEP-II e⁺e^\ensuremath- asymmetric-energy storage ring. The resulting product branching fraction upper limits are B(B⁰\ensuremath→X^\ensuremath-K⁺,X^\ensuremath-\ensuremath→J/\ensuremathψ\ensuremathπ^\ensuremath-\ensuremathπ⁰)<5.4\ifmmode×\else\texttimes\fi10^\ensuremath-6 and B(B^\ensuremath-\ensuremath→X^\ensuremath-K⁰,X^\ensuremath-\ensuremath→J/\ensuremathψ\ensuremathπ^\ensuremath-\ensuremathπ⁰)<22\ifmmode×\else\texttimes\fi10^\ensuremath-6 at the 90% confidence level.
