Evidence for B-→τ-ν̄τ with a semileptonic tagging method
We present a measurement of the decay B-→τ -ν̄τ using a data sample containing 657×106 BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. A sample of B+B- pairs are tagged by reconstructing one B+ meson decaying semileptonically. We detect...
