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

The Belle Collaboration, A. Abdesselam, I. Adachi +461

We report a measurement of 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^{…

Measurement of the $D^{*} (2010)^{+} - D^{+}$ mass difference

The BaBar Collaboration

We measure the mass difference, $Δ m_{+}$ , between the $D^{*} (2010)^{+}$ and the $D^{+}$ using the decay chain $D^{*} (2010)^{+} \to D^{+} π^{0}$ with $D^{+} \to K^{-} π^{+} π^{+}$ . The data were recorded w…

Precise determination of the CKM matrix element $∣ V_{c b} ∣$ with $B ˉ^{0} \to D^{* +} ℓ^{-} ν ˉ_{ℓ}$ decays with hadronic tagging at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +459

The precise determination of the CKM matrix element $∣ V_{c b} ∣$ is important for carrying out tests of the flavour sector of the Standard Model. In this article we prese…

Angular analysis of $B^{0} \to K^{*} (892)^{0} ℓ^{+} ℓ^{-}$

Belle Collaboration, A. Abdesselam, I. Adachi +442

We present a measurement of angular observables, $P_{4}^{'}$ , $P_{5}^{'}$ , $P_{6}^{'}$ , $P_{8}^{'}$ , in the decay $B^{0} \to K^{*} (892)^{0} ℓ^{+} ℓ^{-}$ , where $ℓ^{+} ℓ^{-}$ is either $e^{+} e^{-}$ or $μ^+…

Measurement of the branching ratio of $B ˉ^{0} \to D^{+} τ^{-} ν ˉ_{τ}$ relative to $B ˉ^{0} \to D^{+} ℓ^{-} ν ˉ_{ℓ}$ decays with a semileptonic tagging method

A. Abdesselam, I. Adachi, K. Adamczyk +441

We report a measurement of ratio $R (D^{*}) = B (B ˉ^{0} \to D^{*+} τ^{-} ν ˉ_{τ}) / B (B ˉ^{0} \to D^{*+} ℓ^{-} ν ˉ_{ℓ})$ , where $ℓ$ denot…

Search for Long-Lived Particles in $e^{+} e^{-}$ Collisions

J. P. Lees, others

We present a search for a neutral, long-lived particle $L$ that is produced in $e^{+} e^{-}$ collisions and decays at a significant distance from the $e^{+} e^{-}$ interaction point into var…
