Abstract
A search for the decays Bd,s0 →γγ in 2.95 million hadronic Z decays has been performed using the L3 detector at LEP. No candidates are found in the signal region and upper limits have been set on the branching ratios: Br(Bd0→γ)<3.9×10−5 and Br(Bs0 →γγ) < 14.8 × 10−5 at 90% CL. These are the first limits set on these exclusive rare decays.
