dc.description.abstract | We present measurements of branching fractions for five B -meson decays to two-body charmless final states. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 459 × 10 6 B ¯¯¯ B pairs. The results for branching fractions are, in units of 10 − 6 (upper limits at 90% C.L.), B ( B + → η ρ + ) = 9.9 ± 1.2 ± 0.8 , B ( B 0 → η ′ η ) = 0.5 ± 0.4 ± 0.1 ( < 1.2 ) , B ( B 0 → η π 0 ) = 0.9 ± 0.4 ± 0.1 ( < 1.5 ) , B ( B 0 → η ′ π 0 ) = 0.9 ± 0.4 ± 0.1 ( < 1.5 ) , and B ( B 0 → ω π 0 ) = 0.07 ± 0.26 ± 0.02 ( < 0.5 ) . The first error quoted is statistical and the second systematic. For the η ρ + mode, we measure the charge asymmetry A c h ( B + → η ρ + ) = 0.13 ± 0.11 ± 0.02 . | - |
