Measurement of $R (D)$ and $R (D^{*})$ with a semileptonic tagging method

The Belle Collaboration, G. Caria, P. Urquijo +188

The experimental results on the ratios of branching fractions $R (D) = B (B ˉ \to D τ^{-} ν ˉ_{τ}) / B (B ˉ \to D ℓ^{-} ν ˉ_{ℓ})$ and $\mathcal{R}(D^…

Test of lepton flavor universality and search for lepton flavor violation in $B \to K ℓℓ$ decays

S. Choudhury, S. Sandilya, K. Trabelsi +220

We present measurements of the branching fractions for the decays $B \to K μ^{+} μ^{-}$ and $B \to K e^{+} e^{-}$ , and their ratio ( $R_{K}$ ), using a data sample of 711 $f b^{- 1}$ that…

Test of lepton-flavor universality in $B \to K^{*} ℓ^{+} ℓ^{-}$ decays at Belle

Belle Collaboration, S. Wehle, I. Adachi +179

We present a measurement of $R_{K^{*}}$ , the branching fraction ratio $B (B \to K^{*} μ^{+} μ^{-})$ / $B (B \to K^{*} e^{+} e^{-})$ , for both charged and neutral $B$ meso…
