Measurements of the Branching Fractions of Exclusive Charmless B Meson Decays with eta-prime or omega Mesons
- SLAC
We present the results of searches for B decays to charmless two-body final states containing {eta} or {omega} mesons, based on 20.7 fb{sup -1} of data collected with the BABAR detector. We find the branching fractions {Beta}(B{sup +} {yields} {eta} K{sup +}) = (70 {+-} 8 {+-} 5) x 10{sup -6}, {Beta}(B{sup 0} {yields} {eta} K{sup 0}) = (42{sub -11}{sup +13} {+-} 4) x 10{sup -6}, and {Beta}(B{sup +} {yields} {omega}{pi}{sup +}) = (6.6{sub -1.8}{sup +2.1} {+-} 0.7) x 10{sup -6} where the first error quoted is statistical and the second systematic. We give measurements of four additional modes for which the 90% confidence level upper limits are {Beta}(B{sup 0} {yields} {omega} K{sup 0}) < 13 x 10{sup -6}, {Beta}(B{sup +} {yields} {eta}{pi}{sup +}) < 12 x 10{sup -6}, {Beta}(B{sup +} {yields} {omega} K{sup +}) < 4 x 10{sup -6}, and {Beta}(B{sup 0} {yields} {omega}{pi}{sup 0}) < 3 x 10{sup -6}.
