Observation of B+→D̄*0τ+ντ and evidence for B+→D̄0τ+ντ at Belle

We present measurements of B+→D̄ *0τ+ντ and B+→D̄0τ+ντ decays in a data sample of 657×106 BB̄ pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 446-56+58 B+→D̄*0τ+ντ events with a significance of 8.1 standard deviations, and 146-41+42 B+→D̄0τ+ν τ events wit...
