| Abstract: | Using 383 × 10 6 B ¯¯¯ B pairs from the BABAR data sample, we report results for branching fractions of six charged B -meson decay modes, where a charged kaon recoils against a charmless resonance decaying to K ¯¯¯¯ K ∗ or η π π final states with mass in the range ( 1.2 - 1.8 ) GeV / c 2 . We observe a significant enhancement at the low K ¯¯¯¯ K ∗ invariant mass which is interpreted as B + → η ( 1475 ) K + , find evidence for the decay B + → η ( 1295 ) K + , and place upper limits on the decays B + → η ( 1405 ) K + , B + → f 1 ( 1285 ) K + , B + → f 1 ( 1420 ) K + , and B + → ϕ ( 1680 ) K + . |
