| 英文摘要 | We report the first measurement of the forward-backward asymmetry and the ratios of Wilson coefficients A(9)/A(7) and A(10)/A(7) 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 3.4 sigma. The results are obtained from a data sample containing 386x10(6) (B) over bar pairs that were collected on the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. |
