Observation of the semileptonic decays B→D*τ-ν̄τ and evidence for B→Dτ-ν̄τ

We present measurements of the semileptonic decays B-→D0τ- ν̄τ, B-→D*0τ-ν̄τ, B̄0→D+τ- ν̄τ, and B̄0→D*+τ-ν̄τ, which are potentially sensitive to non-standard model amplitudes. The data sample comprises 232×106 Υ(4S)→BB̄ decays collected with the BABAR detector. From a combined fit to B- and B̄0 chann...
