Evidence for an Excess of B̅ →D[superscript (*)]τ[superscript -]ν̅ [subscript τ] Decays
Based on the full BABAR data sample, we report improved measurements of the ratios R(D[superscript(*)])=B(B̅→D[superscript (*)][bar over τ]ν̅[subscript τ])/B(B̅→D[superscript (*)]ℓ[subscript bar over ℓ]ν̅[subscript ℓ]), where ℓ is either e or μ. These ratios are sensitive to new physics contribution...
