The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represent 465 × 10 6 B ¯¯¯ B pairs produced in e + e − annihilation at the energy of the Υ ( 4 S ) . We find no significant signal and set an upper limit at 90% confidence level on the product of branching fractions B ( B + → a + 1 ( 1260 ) K * 0 ( 892 ) ) × B ( a + 1 ( 1260 ) → π + π − π + ) of 1.8 × 10 − 6 .8 p.application/pdfeng(c) American Physical Society, 2010Física de partículesExperimentsParticle physicsExperimentsinfo:eu-repo/semantics/article6019292019-04-08info:eu-repo/semantics/openAccess
