The analysis was performed on a data sample consisting of 383 × 10 6 B ¯¯¯ B pairs collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We find no significant signal and set an upper limit on the product branching fraction B ( B + → a + 0 π 0 ) × B ( a + 0 → η π + ) of 1.4 × 10 − 6 at the 90% confidence level.8 p.application/pdfeng(c) American Physical Society, 2008Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article5777142019-04-05info:eu-repo/semantics/openAccess
