Abstract

A search has been made for the decays B⁺\ensuremath→\ensuremathφ\ensuremathπ⁺ and B⁰\ensuremath→\ensuremathφ\ensuremathπ⁰ in a data sample of approximately 232\ifmmode×\else\texttimes\fi10⁶ BB pairs recorded at the \ensuremathΥ(4S) resonance with the BABAR detector at the PEP-II B-meson Factory at SLAC. No significant signals have been observed, and therefore upper limits have been set on the branching fractions: B(B⁺\ensuremath→\ensuremathφ\ensuremathπ⁺)<2.4\ifmmode×\else\texttimes\fi10^\ensuremath-7 and B(B⁰\ensuremath→\ensuremathφ\ensuremathπ⁰)<2.8\ifmmode×\else\texttimes\fi10^\ensuremath-7 at 90% probability.
