Measurement of the ratio of branching fractions B(B[bar]0→D*+τ-ν[bar]τ)/B(B[bar]0→D*+μ-ν[bar]μ)
The branching fraction ratio R(D∗)≡B(¯B0→D*+τ−¯ντ)/B(¯B0→D*+μ−¯νμ) is measured using a sample of proton-proton collision data corresponding to 3.0 fb−1 of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode τ−→μ−¯νμντ. The semita...
