Abstract

We report the first measurement of the branching fraction for the inclusive decay [Formula presented], where [Formula presented] is either an electron or a muon, and [Formula presented] is a hadronic recoil system that contains an [Formula presented] quark. We analyzed a data sample of [Formula presented] [Formula presented] meson pairs collected with the Belle detector at the KEKB [Formula presented] asymmetric-energy collider. We find [Formula presented] for dilepton masses greater than [Formula presented].
