Abstract

The decays B⁰ _d, B⁰ _s → e⁺e^-, μ⁺μ^-, e^±μ^∓ are searched for in 3.5 million hadronic Z events, which constitute the full LEP I data sample collected by the L3 detector. No signals are observed, therefore upper limits at the 90% (95%) confidence levels are set on the following branching fractions: Br(B⁰ _d → e⁺e^-) < 1.4(1.8) × 10^-5; Br(B⁰ _s → e⁺e^-) < 5.4(7.0) × 10^-5; Br(B⁰ _d → μ⁺μ^-) < 1.0(1.4) × 10^-5; Br(B⁰ _s → μ⁺μ^-) < 3.8(5.1) × 10^-5; Br(B⁰ _d → e^±μ^∓) < 1.6(2.0) × 10^-5; Br(B⁰ _s → e^±μ^∓) < 4.1(5.3) × 10^-5. The results for B⁰ _s → e⁺e^- and B⁰ _s → e^±μ^∓are the first limits set on these decay modes.

N2 - The decays B0 d, B0 s → e+e-, μ+μ-, e±μ∓ are searched for in 3.5 million hadronic Z events, which constitute the full LEP I data sample collected by the L3 detector. No signals are observed, therefore upper limits at the 90% (95%) confidence levels are set on the following branching fractions: Br(B0 d → e+e-) < 1.4(1.8) × 10-5; Br(B0 s → e+e-) < 5.4(7.0) × 10-5; Br(B0 d → μ+μ-) < 1.0(1.4) × 10-5; Br(B0 s → μ+μ-) < 3.8(5.1) × 10-5; Br(B0 d → e±μ∓) < 1.6(2.0) × 10-5; Br(B0 s → e±μ∓) < 4.1(5.3) × 10-5. The results for B0 s → e+e- and B0 s → e±μ∓are the first limits set on these decay modes.
