- Summary
- The authors have performed a search for the flavor-changing neutral-current decays B → πℓ⁺ℓ⁻, where ℓ⁺ℓ⁻ is either e⁺e⁻ or μ⁺μ⁻, using a sample of 230 million Υ(4S) → B{bar B} decays collected with the BABAR detector. They observe no evidence of a signal and measure the upper limit on the isospin-averaged branching fraction to be Β(B → πℓ⁺ℓ⁻) < 9.1 x 10⁻⁸ at 90% confidence level. They also search for the lepton-flavor-violating decays B → πe{sup ±} μ{sup ∓} and measure an upper limit on the isospin-averaged branching fraction of Β(B → πe{sup ±} μ{sup ∓}) < 9.2 x 10⁻⁸ at 90% confidence level.
