| 英文摘要 | We present a measurement of the time-dependent CP-violating asymmetry in B-0-> K(*0)gamma decays with K-*0-> K(S)(0)pi(0) based on 232x10(6) Upsilon(4S)-> B (B) over bar decays collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at SLAC. In a sample containing 157 +/- 16 signal decays, we measure S(K)(*0)gamma=-0.21 +/- 0.40 +/- 0.05 and C(K)(*0)gamma=-0.40 +/- 0.23 +/- 0.03, where the first error is statistical and the second systematic. We also explore B-0-> K(S)(0)pi(0)gamma decays with 1.1 < m(KS)(0)pi(0)< 1.8 GeV/c(2) and find 59 +/- 13 signal events with S(KS)(0)pi(0)gamma=0.9 +/- 1.0 +/- 0.2 and C(KS)(0)pi(0)gamma=-1.0 +/- 0.5 +/- 0.2. |
