Using a full BABAR data sample of 426 fb−1, we present improved measurements of the ratio ℛ(D(∗)) = ℬ(B̅ → D(∗)τ−ν̅τ)/ ℬ(B̅ → D(∗)ℓℓ−ν̅ℓ), where ℓ is either electron or muon. We measure ℛ(D) = 0.440±0.058±0.042 and ℛ(D∗) = 0.332±0.024±0.018. These ratios exceed the Standard Model predictions by 2:0σ...
