标题： Observation of B Meson Decays to omegapi+, omegaK+, and omegaK0

摘要： 我们给出了B介子衰变到omega pi+，omega K+和omega K0的初步测量结果。 数据是由BABAR探测器记录的，对应于在Upsilon(4S)共振处通过e+e-湮灭产生的88.9x10^6对BBbar。 我们发现所有三个通道都有统计显著信号： B(B->omegapi+)=(5.4+/-1.0+/-0.5)x10^-6，B(B->omegaK+)=(5.0+/-1.0+/-0.4)x10^-6，以及B(B->omegaK0)=(5.3^+1.4_-1.2+/-0.5)x10^-6。 我们还测量了时间积分电荷不对称性A_ch(omegapi+)=0.04+/-0.17+/-0.01和 A_ch(omegaK+)=-0.05+/-0.16+/-0.01。 显示英文摘要

摘要： We present preliminary measurements of B meson decays to omegapi+, omegaK+, and omegaK0. The data were recorded with the BABAR detector and correspond to 88.9x10^6 BBbar pairs produced in e+e- annihilation at the Upsilon(4S) resonance. We find statistically significant signals for all three channels: B(B->omegapi+)=(5.4+/-1.0+/-0.5)x10^-6, B(B->omegaK+)=(5.0+/-1.0+/-0.4)x10^-6, and B(B->omegaK0)=(5.3^+1.4_-1.2+/-0.5)x10^-6. We also measure time-integrated charge asymmetries A_ch(omegapi+)=0.04+/-0.17+/-0.01 and A_ch(omegaK+)=-0.05+/-0.16+/-0.01.
