Search for B+ -> phi pi+ and B0 -> phi pi0 Decays
Abstract
A search has been made for the decays B+ -> phi pi+ and B0->to phi pi0 in a data sample of approximately 232 x 106 B Bbar pairs recorded at the Upsilon(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: BR(B+ ->phi pi+)<2.4 x 10-7 and BR(B0->phi pi0)<2.8 x 10-7 at 90% probability.
