英文摘要	We report the first search for CP-violating decays of the Y(4S) using a data sample that contains 535 x 10(6) Y(4S) mesons with the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. A partial reconstruction technique is employed to enhance the signal sensitivity. No significant signals were observed. We obtain an upper limit of 4 x 10(-7) at the 90% confidence level for the branching fractions of the CP violating modes, Y(4S) -> B-0(B) over bar (0) -> J/psi K-S(0) + J/psi(eta K-c)(S)0. Extrapolating the result, we find that an observation with 5 sigma significance is expected with a 30 ab(-1) data sample, which is within the reach of a future super B factory.
