摘要：

A search for exclusive decays of B-d(0) and B-s(0) mesons has been preformed in the channels B-d(0) --> J eta, B-s(0) --> J eta, B-d(0) --> J(pi)(0) and B-s(0) --> J(pi)(0). The data smaple consisted of more than three and a half million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1995. No candidate events have been observed for any of the modes thus determining upper limits at 90% confidence level: 3.2 x 10(-4) on Br(B-d(0) --> J(pi)(0)) and the first experimental limits: Br(B-d(0) --> J eta) < 1.2 x 10(-3), Br(B-s(0) --> J eta) < 3.8 x 10(-3), Br(B-s(0) --> J pi(0)) < 1.2 x 10(-3).
