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.

Search for the standard model Higgs boson in e+e− interactions at =183 GeV

A search for the Standard Model Higgs boson is performed with the L3 detector at LEP. The data sample, corresponding to a luminosity of 55.3 pb−1, was collected at an average centre-of-mass energy of 182.7GeV. No Higgs signal is observed, leading to a lower limit on the Higgs boson mass of 87.6GeV at the 95% confidence level.
