We report the first measurement of the forward-backward asymmetry and the ratios of Wilson coefficients and in A9/A7 and A10/A7 in B --> K*l+l-, where l represents an electron or a muon. We find evidence for the forward-backward asymmetry with a significance of 3.4sigma. The results are obtained from a data sample containing 386 x 10(6) BB pairs that were collected on the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.
我们报告了在B→K*l+l-过程中（其中l代表电子或μ子），首次对前后不对称性以及威尔逊系数比值A9/A7和A10/A7的测量。我们发现了前后不对称性的证据，显著性为3.4σ。这些结果是从一个包含386×10⁶个BB对的数据样本中获得的，该样本是在KEKB非对称能量e⁺e⁻对撞机上，利用 Belle 探测器在Y(4S)共振处收集的。
