Book excerpt: The authors present preliminary measurements of B meson decays to B[sup+][yields][omega][pi][sup+], B[sup+][yields][omega]K[sup+], and B[sup 0][yields][omega]K[sup 0]. The data were recorded with the BABAR detector and correspond to 88.9 x 10[sup 6] B[bar B] pairs produced in e[sup+]e[sup -] annihilation at the[Upsilon](4S) resonance. They find statistically significant signals for all three channels:[Beta](B[sup+][yields][omega][pi][sup+])= (5.4[+-] 1.0[+-] 0.5) x 10[sup -6], [Beta](B[sup+][yields][omega]K[sup+])= (5.0[+-] 1.0[+-] 0.4) x 10[sup -6], and[Beta](B[sup 0][yields][omega]K[sup 0])= (5.3[sub -1.2][sup+1.4][+-] 0.5) x 10[sup -6]. They also measure time-integrated charge asymmetries[Alpha][sub ch](B[sup+][yields][omega][pi][sup+])= 0.04[+-] 0.17[+-] 0.01 and[Alpha][sub ch](B[sup+][yields][omega]K[sup+])= -0.05[+-] 0.16[+-] 0.01.
