Abstract
We present a study of the charmless semileptonic B-meson decays B+ -> omega l(+) v and B+ -> eta l(+) v. The analysis is based on 3.83 x 10(8) B (B) over bar B pairs recorded at the Gamma(4S) resonance with the BABAR detector. The omega mesons are reconstructed in the channel omega -> pi(+)pi(-)pi(0) and the eta mesons in the channels eta -> pi(+)pi(-)pi(0) and eta -> gamma gamma. We measure the branching fractions B(B+ -> omega l(+) v) = (1.14 +/- 0.16(stat) +/- 0.08(syst)) x 10(-4) and B(B+ -> eta l(+) v) = (0.31 +/- 0.06(stat) +/- 0.08(syst)) x 10(-4).
