Issue Date: | 1-Jan-2003 | Journal Volume: | 91 | Journal Issue: | 26 | Source: | Physical Review Letters | Abstract: | We report the observation of the flavor-changing neutral current decay [Formula presented] and an improved measurement of the decay [Formula presented], where [Formula presented] represents an electron or a muon, with a data sample of [Formula presented] accumulated at the [Formula presented] resonance with the Belle detector at KEKB. The results for the branching fractions are [Formula Presented] and [Formula Presented], where the first error is statistical, the second is systematic and the third is from model dependence. © 2003 The American Physical Society. |
